While this site is dedicated to free speech, the following will not be tolerated: devolving a thread into unrelated political discussion, sockpuppeting (using multiple and/or bogus accounts), disrupting topics without contributing to them, and posting images that could get someone fired in the workplace (an external link is OK, but clearly mark it as Not Safe For Work, or NSFW). If you receive a warning, please take it seriously and either move on to another topic or steer the discussion back to its original RPG-related theme.

The RPGPundit can shut down any thread, topic of discussion, or user in a thread at his pleasure. This part of the site is essentially his house, so keep that in mind.

   Regarding respirators, they are for people like Mistwell, who feels it is other people's concern to protect his safety with porous cloth.  Wear a respirator when you go out, and you will not be inhaling anyone's contaminants, even the tiny little ones that pass right through that porous mask.

Unless the mask is air-tight (e.g., properly fitted, properly worn N-95 mask), a portion of the aerosols will bypass the filter material. The degree of bypass is dependent on the mask and bypass flow areas and their respective pressure drops. A surgical mask (not air-tight, with relatively large gaps and low pressure drops) will not filter small aerosols, as they will follow the flow streamlines through the bypass area. The larger aerosols with enough mass (inertia) to "break out" from flow streamlines and follow the flow through the filter material. Ironically, if the mask isn't air-tight, then then a mask with "tighter" filter material (i.e., with a higher pressure drop across it) will have higher bypass flow and hence more bypass release.

Something else to consider is that what makes an N-95 so effective is that its filter material is specifically designed and manufactured to use electrostatic potential to cause aerosols passing through it to deposit on it. Not something you are going to get from t-shirt or (to the best of my knowledge) surgical mask material. As an aside, I have a colleague who participated in experiments to sterilize N-95 masks with radiation. Turns out that the degree of radiation needed for sterilization also damages the filter material such that it loses it electrostatic potential.

  I am not talking about an N-95, I mean an industrial respirator you wear to spray paint, or a full gas mask.   With removable filters and all.  That is as good as you can get to be safe from anything in the air, and IMO if you blame others for getting you sick and you are not wearing that, you are just a dumbass.
My ED provides North respirators, but they are the half-face models that require separate goggles rather than having a fully sealed faceplate. replacement filters are provided too. Anyone that wants to can purchase their own full-face model, but they can be mighty expensive. Either one takes a lot of discipline to wear for an extended period.

  Oh I agree with that.  A respirator is a bitch to wear, it is hot and not comfortable, at least mine isnt, as rubber does not breathe.  But respirators and some sweet goggles like kids used to wear in wood shop and you are set, hardware stores carry respirators, and you can get a gas mask for a couple hundred bucks.  Wearing a gas mask is no fun either, and I remember after 3-4 hours I was not loving it.  The really nice full face respirators (read, comfortable to wear..and comfort being on a relative scale) are fairly expensive.   My point though, is anyone who really feels there is an issue where their health is at risk, they should get one because even an expensive one is worth a lot less than their lives...if they really believe that they could die from other people not wearing a mask or not being vaxxed.

Yeah I wear a respirator when working in our attic, and I hate it. I mean it's fine for the first 10 mins, but damn those things get hot, and it takes a lot more energy to breath through one.

  Yes, because of the filter that actually keeps airborne things from entering your body.  Just wearing one is not great, and working with one on is miserable, but then working with anything over your face is pretty miserable.  A whole subsegment of bro science hypoxic training took off a few years ago around training with a respirator like training mask on.  Fucking fighters will do ANYTHING to avoid putting in road miles.

I'm wondering that too. Is it because he likes FG but not the message, or because he doesn't like FG, or something else?

It doesn't show Chris Griffin getting the jab, suffering heart inflammation and dying a few days later.

How in the hell does someone get away with a PSA or advertisement of a medicine like the Pfizer, Moderna, or J&J vaccine without including disclaimers about the side effects?

Because even in the extremely rare instance of myocarditis from the vaccine, almost all of them clear up without much trouble? Or are you playing the game of "Most people survive Covid just fine, but I am going to misrepresent the vaccinated as often dying from the vaccine?"

The idea that entertainment personalities and cartoon dogs are dispensing medical advice and information.

The problem isn't that people don't understand how vaccines work. The problem is the government and media have intentionally lied and misled the public on the topic.

Seth MacFarlane should stick to rape jokes. Giggity.
The notion of an exclusionary and hostile RPG community is a fever dream of zealots who view all social dynamics through a narrow keyhole of structural oppression.

I can see what you mean about objecting to entertainers putting in their views on health issues, whether that entertainer is Seth MacFarlane or Tucker Carlson.

That's not what FOX itself says about him. They specifically call him an entertainer, and that no reasonable person should take what he says seriously.
