I always find it funny when "fascist" is apparently the term for someone pointing out simple facts or science or math.

It's one of those things where you can see that name calling doesn't promote any argument, when it ends up being that whatever derogatory term is conflated with people who actually know things.

"Oh you can do calculus? Well you must be a <insert slur>!"

Well apparently those <slur> people are pretty smart and informed! Go figure!
