That doesn't mean society needs to celebrate it with sex parades... err, "pride" parades, or encourage it in any way, any more than polygamy, wife swapping, or any other sexual proclivity...
Society does not do that. Gays have gay parades. You can mind your own business and not be so judgemental. They have lots of troubles without people like you making things worse. I do not understand the pride of being gay or straight. It is just your reality and it only requires acceptance. Gays were in hiding for a long, long time. It is something new for them to be gay in public. They lived in the dark for centuries.
