Eh, I'd say gay, lesbian, and bi people should have a "day" like everyone else -- maybe even a weekend, at a stretch -- because non-hetero have been part of our culture for generations, and they have contributed to culture, science, and the like... but an entire fucking month? And that month is to celebrate utter degeneracy (fucking on the streets in fetish gear, fucking openly in front of children, et cetera) and forcing viewpoints/propaganda on everyone else? No way.
Additionally, since the Alphabet Soup movement has become Groomers United now, the ordinary people with sanity/common sense who just happen to be gay, lesbian, or bi want nothing to do with that fucking mess -- these people are the ones such a day or weekend would be dedicated to, not the freaks in fetish gear who walk down mainstreet, openly fucking on grass, and wearing all the colours of a rainbow like a pack of Skittles.
