Correct, he's a football manager. He's not a PR man or a public speaker. I don't think he should have spoken out, but he's not wrong.
It's obvious that he was having a dig at the minitory of dinlos, and I am struggling to understand why anyone who isn't in that minority is getting upset on other people's behalf. If anyone is in that minority and are upset by it, good, and hopefully they'll learn from it.
Personally, I like that he's chippy. He ain't nice, and we don't play nice anymore. Thank fuck for that frankly.
