Does same-sex marriage affect you? Does it harm your marriage? Make you love your wife less? Love your children less? More likely to get divorced? Does God approve of your union any less? Does it harm my marriage? How about your neighbor? Is your neighbor's marriage no longer sacred?
If you can't tell me any specific harm done to you or anyone else by two dudes having their relationship recognized by the government, where do you get off demanding that their relationship be illegal? And why do you think this is about sex? Marriage isn't sex, I don't know if anyone told you, but gay people already have sex. Are you seriously suggesting sodomy should be illegal again? And you want to know why you're called a fascist?
Grow up, realize when something isn't your business, and move on with your life. Gay people getting married doesn't affect you, so stop fretting over it.
