Preventing enjoyment is a textbook shill tactic. When you find people who go out of their way to shit on things in an effort to prevent people from enjoying it, you've identified a black pilled shit bag who is worthless to himself and the world, or a jew/shill.

Make your humor more obvious. I am constantly hearing people talk out of thier ass about shit that they are just imagining. It needs to get called out. If you play along with people's delusions it reinforces them. Then they become increasingly insufferable.
