That's a problem. What are we willing to believe about people who hold or practice differently than us?
Did you see the actual paper? Were you told where this was handed out?
I wouldn't be surprised if this is real, and it's not a problem that I think so because there is plenty of people who are extremist today's days and they blame there Rebbi's there leaders for the things they do!!
The "satmer rebbi" z"l used to cry bitterly when he heard about IDF soldier's that where killed, and today there are plenty of people who call them self's his "chasidim" and they jump on the streets when soldier's are killed and give out doughnuts in school when Rav shteinman zatza"l passed away!!
