Why are Eminem fans so annoying OMG ?

I mean I used to be a fan till I felt like some ppl were worshipping like in a religion or sthg.whenever I listen to other rappers there always comment like em would kill him any day or he's **** compare to em,why is that so 2pac fans are never going on every YouTube video to say that nor are nas and Jay zfans.and whenever I disagree with him being the best of all time ppl call me racist???
