Mod80, I’m not sure that’s true. I think the “assur” cries are becoming more and more of a problem in the Jewish community in general. People aren’t properly educated and if they hear something that is different from what they specifically know, they don’t question “could it be ok” but rather say “assur, treif” etc. Each Rav paskens differently, so it may be assur for you, but it doesn’t mean its always assur.
And the truth is, if something isn’t assur, it usually is muttar. The question is if its appropriate…and that’s more of a case by case basis.
