Particularly since their rules tweaks have literally become official 5e rules in two books now, as opposed to your house rules which have appeared in zero official rules.
What rules did WotC change to conform to Mercer's house rules?
Did WotC present the change as the new official rule or offer it up as a variant concept?
I'm legitimately asking because I hadn't heard of Mercer's house rules going beyond his own Kickstarter book.
In fact, several important figures on the Left have gone so far as to say "I actually DO believe Tara Reade, but I just think it's far more important to beat Donald Trump, so I'm still going to totally support someone I think is a sexual abuser if it will stop the Orange Man".
That's the official DNC party line now.
We believe all wahmens, but Orange Man super bad so vote for sticky fingers!
And that is absolutely pure hypocrisy.
And I don't think anyone cares. Trump supporters aren't going to vote for Biden if he's innocent and his supporters consider getting him in the White House more important than any scandal whatsoever.
One question might be what do the undecideds think, but most of them don't vote. Thus, the bigger question is how MUCH scandal and hypocrisy is needed to get enough Democrats to stay home on election day.
