Again... Being Queer doesn't give you a pass to bigotry. You aren't immune to fetishizing just because you are part of the LGBT+ community. It's not how it works. If it were, we wouldn't be here having this discussion in the first place.
Not to mention that, just like I and @Stardust previously stated, you, YOURSELF said, I quote: "he is a lovely uke". If that isn't problematic, I don't know what is. Again, these were your own words. You didn't just say "the Art looks like the one most commonly used in BLs". No. You CLEARLY said "he is a lovely uke". That IS fetishization. And that is not to mention how, you being a Queer person should be the FIRST to know how MUCH of an issue reducing characters to mere sexual positions is. Yet here you are. Indulging in and encouraging this toxicity.
Bruh i read too much yaoi so when i see gallahan i immediately fall for him and thinking he is a lovely uke
