Is your family member Google Ad Sense?
"I see you spent a week researching PSUs for your computer and I see that you finally bought one. Would you like to buy a PSU? because even though we know you bought one we'll be showing you nothing but ads for PSUs for the foreseeable future."
Am I weird in that I think it's weird to announce that kind of thing on a dating profile? Like, I'm on all the dating apps and people generally don't get access to me until there's a mutual agreement to match, right? Unless you're swiping on everyone or they're actively trying to hide it, are you matching with a lot of trans folk? Are you so inundated by these matches that you feel the need to announce these preferences up front? I can't imagine it's so many that you can't just have a polite conversation when it comes up and explain the preference? It's the whole need to announce it, knowing how it could come off, that makes people question the intent. If you were at the bar and someone you're attracted to comes up to talk, do you stop them and say "before you go any further, know that I only date cis people."?
