If you purchase a firearm for self defense or other practical purposes, you'll want to practice on a regular basis. Unless you have a way to practice without going to a range (like if you live in an area where it'd be legal to just go set up cans in the back yard) I recommend asking around for range recommendations so you can find one that has a culture that will welcome you.

I know people don't like reddit, but that's a pretty niche question for a platform this small. Asking the liberal gunowners subreddit, or the subreddit for your local community if there are any ranges they'd reccomend as a place for a queer or progressive person to go safely practice on a regular basis could be really helpful. There's likely also a queer gunowners community, but I don't know without looking what that'd be called.

If you know any folks in your actual area that shoot, chatting with them is a great way to get local advice, and they might be willing to go to ranges with you and help you find a place that's welcoming. Its a lot easier to step into an unfamiliar place with someone next to you, especially if they're already used to going to ranges and know how to navigate that space.

For me, I could probably ask the kink community in my area as I know there are some veterans in that crowd who could take me with if I were looking for a place to go shooting as a queer person.
