Most frum Jews actually can't tell chasidim apart, I mean doesn't karlin dress a little like the litvish? I was surprised as a youngster when I saw litvisher rabbanim in america wearing kappotes.
If lehavdil fish made a concert, you can't scapegoat fish fans, well you could say that fans of fish are morons etc.
But by chasidim, you can point fingers at a group, a leadership..this wasnt like a surprise birthday party.
And the gloating about it?!? Are you crazy?!?
