Fair call mate, he might be your ally but sadly he’s not mine. I’m not sure if you’re LGBTQIA+, but if you’ve spent time in the community you’ll know that not even all of those who identify as queer or non-cis support one another. To the best of my knowledge May doesn’t openly identify as queer himself, and thinking that he’s an ally just because he’s been friends with gay and/or bi men isn’t necessarily the best indicator that he’s an ally to all peoples. Personally, I feel like that argument is pretty similar to “I can’t be racist because I have a ____ friend”.
