In that case, I don’t think it’s fair to describe yourself as someone who “doesn’t care”. I think when you say that you don’t care, it can come off as not caring if someone is being a piece of shit towards your gay friends. “I don’t care if you’re gay” can sound like “I don’t care if you get antagonized for being gay”, and I think the fact that you would stand up for your gay friends shows that you do care that they are gay, you care that that is seen as something worth standing up for and protecting. Saying you don’t care is minimizing the extent to which you do care.
That never made sense to me. X is the shape of two people hugging and O is the shape of pursed lips.
