I say who cares whether he was asked to air his views or not. He may have volunteered or he may not have. Who cares.
His views on racism now is that it still goes on in football. He makes a point in his articles about Norwich or whoever and then someone insults him about something that has nothing to do with football.
If you don't like his view on that then fine but it's no big deal and it's not strange that he says something.
If he is irrelevant then he was irrelevant before that article. I don't think i've seen him write on racism before. It's mainly football and tactics or whatever and that is why he is relevant. If he is a crap pundit then this article won't change it and it won't make him any more relevant.
Anyway, if racism is largely gone from England as you say, then Bright was hired due to his talent and his ability to do the job well. Therefore he is relevant.
