I was asked to jump in on a public game last night in a bar. It was 5e. I am an old guy (51), grizzled, 6'4", most people think I am a viking or really into the show/lifestyle. I sat next to a nice young gay man, we all helped a lady in her 60s that was curious about gaming. Everyone had fun. It was really that easy. I was asked to DM but had a 5 minute chat with the guy that wanted to and he did a great job. I will say it again, EVERYONE HAD FUN. Gaming doesn't have to be about throwing in adjectives and telling people they cannot play your game, to me, it should be about setting aside our differences and having fun.
When I started gaming I was an outcast, not by choice. Now people that make themselves stand out want to dictate who can or cannot play games instead of having the courage to just be decent to others.
And technically, in the disclaimer for their game they make it unplayable by everyone because technically, everyone IS a bigot: big·ot
/ˈbiɡət/
noun
a person who is intolerant toward those holding different opinions.
Are they not intolerant of other people's beliefs by labeling and dismissing people?
