Having been told some of the worst tweets, I am not surprised he has been suspended, pending an investigation. 18 and 19 and not just 1 or 2.
You seem to be very easily excusing racism and sexism and blasting the people who don't, instead of looking at the problem here?
People won;t have waited 10 years, someone will have looked because he was becoming of note. If he had any sense, he'd have deleted that account and started life afresh, but then, maybe he still believes the racist and sexist stuff he tweeted.
Really surprised at your take on this.
