He went the entirety of SSLP without even using the word "faggot" or "fag" once. On MMLP, he used it several times (forgot the exact count), with roughly half of them as insults to ICP in response to them calling him gay in "Slim Anus." The only time slurs were used in an actual "gay-bashing" context were the sarcastic lines in "Criminal," a context which should have been clear to any non-idiot after the intro. The very point of that song was to make the exact opposite point. He actually hates gays the same way as he is actually going to kill anyone who believes that he's going to kill someone because he said it on a track.
On TES, the few times he used it were in an analytical context, such as White America ("actin like I'm the first rapper to smack a bitch or say, 'faggot?'"), with the exception of using it to insult Moby.
Where's the gay bashing?
Eminem actually bashing gay people outside the context of a disclaimer in the intro denoting sarcasm is a relatively new phenomenon for him...a post-pills phenomenon in which he vaguely remembers controversy involving gays over lyrics.
