> a plane half full of Hasidic Jews (the ones refusing to board because they're still praying and knocking their head against the wall, and refuse to sit next to women).

I don't know why you've decided to explain what is a Hasidic jew in that way (or at all). However I hope you can at least understand in retrospect why describing a religious group as people who all follow some negative behavior is promoting hate towards all members of that group, regardless of their actions.
