We just finished up our college search for D17, who is straight but a very committed LGBTQ+ advocate. She gravitated towards LACs and small universities in the Midwest. Some of what I will say is based on personal experience, some based on what I’ve picked up here. I can’t speak to the math departments because that wasn’t a priority for my D.
St. Olaf - a lovely school and your son’s stats would put him in the running for the Buntrock merit scholarship and possibly a music scholarship. Its Lutheran denomination is the more liberal one - supports gay marriage, ordination of gay clergy, etc. We know somebody who went there who is an atheist and she said it was very inclusive socially and politically and not heavy handed WRT religion. The math and music there checks out. Merit aid was very generous - about half of COA.
Oberlin - This was the school that first came to mind when I began reading your post. I would encourage your son to keep an open mind about the politics - I think the media loves to pounce on Oberlin and blow things out of proportion. Have him spend some time with the Oberlin Student Blogs - a wide range of kids are represented there. Their academic and extracurricular interests may differ but they seem universally kind, intellectually curious, and open-minded. I can’t speak to the math dept but I know Oberlin is strong in the sciences, CS, and neuroscience. It is a truly accepting, live-and-let-live, community and gender identity /sexual preference is a complete non-issue as far as I can tell. Regular merit scholarships go up to 25K; I hear there is a named math/science scholarship (Stern?) that goes up to 30K. Kids are intellectually curious but more collaborative than competitive. My D visited twice and will be attending in the fall. I would try to have him visit before ruling it out if the math department meets his needs.
Macalester - low key urban with an upscale residential neighborhood on one side of campus that stretches to the Mississippi River - about a 25-30 minute walk away with nice biking and walking trails. Very inclusive campus. No less left-leaning than Oberlin, IMO. Strong IR and study abroad programs that emphasize the developing world.
She also applied to College of Wooster and Dickinson and they didn’t quite meet her “life of the mind” threshold.
Wesleyan - lots of cross admits with Oberlin. Equally left-leaning if not more so. Minimal distribution requirements and you can design your own major if you want. Didn’t click with D, didn’t apply. Very gay friendly.
Vassar - this D loved but the financials didn’t work out for us, so she didn’t apply. Student guide was very down to earth and smart without being pretentious about it. Gorgeous campus, stunning library and quality art museum. Gay friendly. Your son would get an admissions boost because fewer males apply and attend. Gender neutral bathrooms.
Finally, perhaps more urban that his ideal but a good place for math and music is Case Western Reserve University. About 5-6K undergrads, nerdy collaborative vibe, lots of culture nearby. Yes it’s in Cleveland but in a neighborhood with nearby museums, parks, and a botanical garden, and Lake Erie is nearby. There’s a cool public access Maker space if he’s into that. Case students can take classes at Cleveland Institute of Music. Good merit aid (show interest and apply non-binding EA for best chances). Case does mandatory micro-aggression training as part of its freshman orientation, if that matters. D found it more diverse than the LACs she visited, both in terms of socioeconomic class and race (high % of Asians and visible presence of black and Hispanic students).
The following is not based on direct personal experience:
You also might want to check out schools in the Pacific Northwest, if he wants to avoid hot weather. University of Puget Sound, Lewis & Clark, Willamette, and Whitman come to mind. Probably in the safety zone for your child - he’d stand a good chance of merit scholarships at any of them.
For east coast, maybe try Bard or Skidmore or possibly Sarah Lawrence. I think Skidmore has merit scholarships for music and STEM. Sarah Lawrence has merit money and is eager to attract more male students.
For midwest - Grinnell and possibly Beloit. Also Ohio University in Athens has an Honors Program that is tutorial based. It’s a bigger school and definitely has sports and Greek life. But it might be worth a look.
I suspect that Swarthmore or Reed might be more intense than your kid is seeking. Ditto for Chicago.
Finally - I would take the size of school into account. Acceptance and inclusion is one thing. The size of the dating pool is another. Let’s assume 10% of the student population is gay and half of them are male. If the school has 1200 kids, you’re talking a total dating pool of around 60. If you’re in an urban area with other schools like the Twin Cities or Cleveland or Boston, that opens things up a bit. If you’re in a small rural town, not so much.
Among LACs, St Olaf and Oberlin are larger than the norm, with about 3,000 students each.
