The entire region is pretty LGBTQ+ friendly. Allentown has the Bradbury Sullivan LGBTQ Community Center, which has a lot of events, support groups, programs, meetups, etc. Bethlehem has the more artsy and foody scene, which is nice (it's a great restaurant town), and there's a lot of colleges in the area, which also makes it more LGBTQ+ friendly. There's also Lehigh Valley Pride every year, and the pro sports teams have an LGBTQ+ night as well. I live in Bethlehem, which I like better than Allentown (but there are nice things in Allentown too!). Obviously, it's hard to escape homophobia no matter where you go in the world, but as an out genderqueer person, I feel safe and welcomed here.
