I have no reason why. But here’s a picture of Eminem and Elton John holding hands.
At the time Eminem was being accused of being a massive homophobe due to his lyrics (an accurate assessment I’d say). Elton John decided to team up with him at a music awards ceremony for a performance of Stan. Some people hated that he did that, others liked it. I tend to think it’s generally a good idea to work towards creating a dialogue with people even where it seems like a lost cause. It can take a strong and confident person to bridge that gap though.
