it is semantics - you generalised the behaviour of a group of people based on an attribute - which isn't actually clear from your post. Perhaps I could ask: what is so Jewish about the video in question? I may have been too quick to judge you and will readily apologise if I can understand: what was so Jewish about that video?

but you can generalize a group of peoples behavior but certainly not all of those people will behave exactly the video is about jewish obsession with victimhood and particularly the holohoax
