This is one of the weirdest threads in quite awhile. I don't think I've seen this many strawmen or bizarre arguments in a long time and it's not even over something important or relevant. The most weird being the idea that SJWs are fans of Eminem, WTF? Not to mention Eminem ceased being relevant long before SJWs were even a thing.
No one said SJWs are fans of Eminem... but a number of news articles appeared saying that SJWs on Twitter were celebrating when Eminem won a grammy that Iggy Azalea was expected to win. Granted, they were more celebrating Iggy's loss than Eminem's win, but the idea that either one of them is much better than the other is pretty suspect, IMO. I would hardly say a guy who's still winning awards and putting out hit songs is irrelevant. Oh so that's what this is about. I put about as much credibility in the Grammys as the MTV Movie Awards (which gave Kristen Stewart the Best Actress award four times for her performance in Twilight) and don't care one iota about hip hop music at all, so I can easily miss it. As for Eminem, he's struck me as a leftover 90s relic, he might still be well known, but it's like saying Aerosmith was still a big band in the 90s. Maybe not technically untrue but you know....
As for Iggy, I'll point out that rapping in an Australian accent sounds silly, so if someone is going to fake one, it's likely to be the most common one used in rap music, so yes reminiscent of black rappers. It seems kind of weird, not to mention also racist to insist that she rap in one of the many white American accents instead that is no more natural to her anyway. Now if you want to attack her simply for being terrible, go ahead.
