if this is something you need to be told on the internet you got bigger problems. far right and far left have become meaningless terms mostly i just see it be used as a synonym for bad people i don't like just like calling someone a Nazi or a racist it just makes you more suspicious of the people doing it because they play with the definitions of words and it makes you automatically pay more attention to how they use these words and if your suspicions are confirmed you can just outright dismiss what this person is saying. this is universal no matter what side or what group does it.
