The "you" wasn't directed to you lol its a statement for everyone. Also, stating "2023" is irrelevant because it doesn't mean anything at all.
Grindr is notorious for hookups and crazy shit; but mostly for hookups. Majority of people go there with a goal in mind, sex. So putting your preference on their profiles would save time for everyone.
Stating your preference is your right in every way. I'm not sure if YOU get a lot of messages on Grindr, which I doubt, having to reply to every single person is exhausting. The preference on the profile will help with "filtering" those messages because as I said it helps save everyone time.
Types/preferences are specifics by the way lol everyone is entitled to what they want and what they prefer. Don't condemn him just because he's attracted to a certain type.
