I haven't been listening to Morrissey's music for that long, but when watching concert footage I noticed that he sometimes phrases things oddly and mispronounces words when talking to the audience. For some reason, he reminds me of some of my friends in academia who are all brilliant in one way or another and often write well but sometimes have trouble expressing themselves in speech, especially about topics outside their field of expertise. I know that when I get nervous, I sometimes say things that I don't actually mean or that sound harsher than I intended, because I feel I have to say something but have trouble finding the right words quickly.
I do think that some of the issues that he raises should perhaps rather be seen as discussion topics or observations. For instance, I personally do not think that people should stick to their own race/culture/ethnicity but looking around me in this multicultural city that I live in, I can see that many people seem to prefer the company of people who are in one way or another similar to them. Neither do I think that raising questions about why a young actor attends a showbiz party by himself should be interpreted as Morrissey supporting Kevin Spacey.
Then again, you would think that after so many years in the public eye, Morrissey should know better. If he really does not want to be misunderstood, he should either think before he speaks or have someone with better judgment sit in with his interviews and interrupt him when he goes of the rails (I mean, listen to the Der Spiegel interview). And why even speak out about race or the Me Too movement; I much rather hear him talk about his life, his creative process, literature or his clothing choices!
