So the whole “I’m superior because I belong to Group X” thing makes this guy different than the fundie who claims “I’m superior because I belong to Group Y”…how?

You know how atheists point & laugh at religious people who mock other religions’ beliefs because they see all beliefs as “bronze age fairy tales” (or whatever)? Well, IMO if one’s pushback includes being every bit as intolerant, obnoxious & divisive as the people one is criticizing, then everyone is basically acting the same and no group gets to lay claim to the moral high ground.
