"KKK members think they are performing a public service by being exclusionary"

This is my exact point. A lot of organizations believe they are performing a public service by being exclusionary. That doesn't mean that they are the equivalent of the KKK. Again, your example doesn't work. You've basically been arguing a fallacy this whole time.

"And your Hitler example only works if I was a Nazi that liked peanut butter, and getting pissed on by an underage niece like Hitler did"

My whole point is that it DOESN'T work.
