I also don't think it makes sense that people who haven't even taken history as a major, need to be taught each and every phrase that was used by a fanatic group.

A lot of these words, phrases and symbols tend to be taken from stuff that meant well in the past or even now. See swastika, svaha^[which I am not sure of the Nazi reference, but it was being chanted by people being portrayed as Nazis in a game].

Just knowing those terms, while might help prevent them from being used in accidental cases, is not as important as being able to recognise the pattern of peoples' actual actions.
Because a group that has copied stuff from other traditions, can always do that again with other sources, to replace that stuff.

It's important that out of history, we make sure to identify the part that we actually need to be against, which is the specific actions that cause grief back then, instead of just picking each and every unrelated thing, which any new group can simply replace, while also getting to keep the original grievous actions.
This is also to prevent us from getting our willpower drained from always getting outraged by multiple instances of minor similarities that are much more probable to be a false +ive, to have the power to push back when we find the actual problem creators.
