Discussion I'm tired of Sith! (and I don't mean all darksiders!)

I am absolutely sick of the idea that Sith are as fundamental to the GFFA as The Force itself! Factions DO die out! Sith is an idea, you say? Nah, that's just Kreia being insane. What's the difference between Sith and darksiders, you ask? Same as the difference between anti-semites and Nazis! Am I the only one who's smart enough to tell the difference between a faction and a personality type?
