If homosexuals had the same attitude and didn't shove the gay agenda down everyone's throats via judicial fiat, bias laws, school indoctrination, gay pride parades, and so on, no one would know or care what they do.
Unfortunately, they have no wish to keep it private. Maybe some do, but enough don't so that the activists and their supporters are rapidly trying to change the world into one that suits them.
It's my understanding that these are primarily "big city" events and issues based on local community standards. Are there a gay pride parades in NYC and SF -- yep, because they are part of the community.
There are gay pride parades all over the place, not just in a few big cities. They are scenes of debaucery and public sex.
But that's not the main problem; indoctrination in thousands of schools is much more dangerous. That and the push to legalize same sex marriage, homosexual adoption and foster parenting. Another extremely dangerous goal of homosexual activists and their assistants is the creation of "hate crimes" laws (now everywhere) with the next step being promoted, "hate speech" laws, as in Canada.
Either you really don't know this (unlikely) or you think these benign or even laudatory.
