How would you feel if on St. Patricks Day you saw people dressed like a Rabbonim drinking straight out of a keg of beer? Would you think it was funny if at the next “rainbow coalition” parade people dressed up like chassidim? You might think it is funny, they dont.
I remember, when I was in high school, there were some fellow who liked heckling one of the english teachers, a devout catholic. One day, to get under his skin they asked if they could “go to the pope” (the previous popes name was john). everyone thought this was so clever and witty, until the next day the teacher announced that he had to make a quick stop at the rabbi. Suddenly everyone was insulted and annoyed (he actually DID go to the office, but thats a separate story).
