considering becoming a flamer or the obvious gay guy

ill start by saying i have zero "gaydar". i just assume everyone i meet is straight. i have trouble hitting on other men cause of well "reasons". i really despise gay hookup sites. so i figure my best bet would be to put myself out there like a billboard and hope something worthwhile happens. sure its very stereotypical but im sure it has its advantages for finding relationships. the problem is ive spent most of my life not really being out to anyone. how would i even start? im a hermit who stays inside on the internet lurking for days. i only ever go out for work and to ride my motorcycle. no one i know would describe me as a flashy person. would i just throw rainbow colors on everything? i only ever where black with more black and other dark stuff. im not good with matching color schemes. also a big part of me wants to know what its like being that guy religious bigots and assholes hate. my very presence would get under their skin like a thorn in their side.
