Turkey is actively killing and repressing the kurds of Syria, such as Rojava, so if we’re boycotting US manufacturers, might be good to avoid turkish one’s too if possible, to deprive their government of tax revenue.
I’m not really sure if there is an ‘ethical’ choice with the big manufacturers anywhere, just different degrees of bad, though definitely worth indirectly supporting the less bad option.
You could opt for small boutique builders that explicitly support leftists and trans, like KE Arms, but those are few and far between. Best resource I can find is this list from the liberalgunowners reddit wiki.
Alternatively, opt for buying used guns from lefitist gun stores (if you have one near you, or can order from them online to a local ffl). That’s probably the best option from a cost and ethics perspective.
I will personally vouch for Russell at KE Arms; he genuinely believes that the second amendment is for all people, regardless of race, gender identity, sexual orientation, or religion. He’s a good dude, IMO.
But fundamentally, yeah, it’s nearly impossible to buy a firearm that is 100% ethical. I know that Karl Kasarda (InRangeTV) likes Desert Tech, because they’ve been good to IRTV and haven’t given him shit about politics, religion, or affiliation with marginalized groups. I don’t like Desert Tech, because they’re run by the Kingston Clan, which is a fundamentalist Mormon cult. I’m also unwilling to buy from Daniel Defense, because they actively market themselves as being a “Christian corporation”, and I oppose that kind of religious bullshittery.
Point is, you gotta pick and choose.
