Iacisrmma – I wrote that that sentence was a joke.
bmyer – You may be right about that. I should have qualified that statement and allowed for the possibility that there may be other opinions. I actually did think that all Sefardim held that way, but after I posted, I was cleaning my sefarim shelves for Pesach and came across a sefer on hilchos Kashrus. I opened it up and on the page I opened up to it said that not all sefardim hold this way (I didn’t look up his source, however).
Joseph – This was in Israel. You are not supposed to be able to force someone to do something against halacha. If there are other opinions, then you are right. But I might not be remembering the details precisely – maybe if the guy was sefardi, they simply pointed out the issue to him.
