Unfortunately you're talking to the wrong lad mate. I'm a big trade unionist, been on plenty of marches, was quite involved in the movement to free Nazanin Zaghari-Ratcliffe etc. Also got plenty of mates who are LGBTQ+. So yes, if Sunderland was taken over I'd guarantee you I wouldn't be off to the match anymore, even if I was in an absolutely tiny minority on that one.
But it's not continuing to support your club that's shocking to be to be honest. I dare say most would do that. It's that you're so morally bankrupt you'd openly admit you'd pretend to care about sportswashing out of pure spite and jealousy if Sunderland were hypotheticaly taken over. The cognitive dissonance you must feel on a daily basis to twist yourself into a position where you can openly admit that on a public forum is incredible.
