If it's punk yer wantin, you'll want Dead Kennedys and MDC - both old bands (MDC is still kicking as I understand it, tho) but lots and lots of highly relevant stuff.
Notable: on their first LP, Millions Of Dead Cops, which came out in 1984 if I recall correctly, there is a trans-positive tune called America's So Straight. You wanna talk ahead of the curve...
