So as a homophobic and intolerant person towards gay people, of course it is completely fine to keep old traditions. Being gay or straight isn't a choice, so maybe put yourself in the shoes of a gay person. What are your options? Pretend to be straight to appease people that hate you, or have less rights?
Being tolerant towards homosexuality is one thing, and recognizing homosexual marriage as a regular marriage is another. Please don't confuse between the two. Personally, I don't care what the gays do in their privacy. But the problem arises when they want to have homosexual orgies in the public, and gay pride parades in the metro cities.
