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.
I can't imagine there'd be a big enough gay population in most second tier cities to form a parade much less spectators to line up and watch it.
The school thing is local and up to the community or majority of the community.
