On top of all that America also just actively persecutes queer people. People will say "oh that's just the republicans" as if that isn't half the country and it's not just the republicans, but a large group of democrats. Then they'll say "oh, but we're not as bad as [enemy of the week]" which funnily enough is actually a whatabouterismerino, but also not really a valid argument if you're saying it's okay to bomb a country if they're mean to queer people. So it's okay to be kinda mean to queer people?
On top of that there's also the fact that some of the US' closest allies are countries like Saudi Arabia, not to mention the many far right anti-lgbtq dictators the state has installed over the years.
On top of that the US has only recently gotten "good" on queer rights. Homosexuality wasn't decriminalised in the whole of the US until 2003 (and we're not talking some weird little forgotten law, it wasn't until a supreme court decision forced several states to finally stop being bigoted.)
At the same time the GDR had decriminalised homosexuality by 1957 and with constitutional reform fully legal by 1968 
The GDR did this despite inheriting the nazis legal code (according to a wikipedia source which I will not fact check.)
Would it have been acceptable, nay morally right, for the GDR to bomb the US?
definitely, but not just because of da gays
Hey I always appreciate feedback. I was also afraid that if I wrote "the south" some umm achually dork would correct me that technically [state] didn't decriminalise sodomy, but it did decriminalise female homosexuality or some other pedantic detail like that.
Turns out it seems to be the other way around, despite decriminalising it, persecution continued. Who would have guessed? I certainly wouldn't have guessed the police decided to just continue to punish people under actually unconstitutional laws (genuinely, that baton rouge thing is wild to me.)
