Mercer's wife is clearly a source of a lot of the super gay shit. You can see his shift from kind of "Hey I love DnD" to "Hey I love DnD and lets make every 4th character gay/trans/retarded"
Had a playgroup a couple of years back that started off normally enough, with a couple of dudes playing girls and what not. Completely fine. Then one of the "guys" started talking about how his teaching role was reducing his hours as an assistant because they felt his gender fluidity was impacting class. Guy showed up to the next session wearing pride-parade tier makeup and complained briefly about his gender journey and how it was impacting his work life. Another "guy" in the group (oddly enough, the other dude who was playing a female character) came out as gay to the group and started actively trying to romance the two other actual males who weren't clearly headjobs ingame.
GM thought it was awesome and continued to interject tons of gay/etc shit into every encounter, complete with constantly trying to have sentient gear that was incredibly gay/etc. Every bartender was a lesbian, half the dudes in town were married to other dudes, etc. I quit and the two coworkers I had in the group quit as well. It went from basically a normal DND game to the most faggoty shit possible. Bohemian Grove and Nixon faggotry.
I am 100% positive none of these people even thought about playing DnD before Critical Role came out. My opinion is it has been a net negative for tabletop roleplaying as a whole. They literally let the floodgays open.
