If this is truly what they want, I'm all for it. But past practices show that what they want is not acceptance but legitimacy. If a majority of people do not agree with them, they find a sympathetic official to interpret what they want as legal. Most times this official is a part of their lifestyle.
So I guess a pedophile can claim this also. Soon other "alternative lifestyles" will be represented. The man in love with animals will be allowed to marry and add his beast to our medical insurance, and maybe allow the animal to vote.
Does this sound crazy? Ten years ago gays and lesbians couldn't get married. As a Christian, I guess I practice an "alternative lifestyle," too.
Gays ask for tolerance but give nothing in return. If I don't accept their "lifestyle," I'm a homophobe. If you don't accept mine, I can't call you anything because then I'm a "hater." It seems like we have to be tolerant to everybody but Christians.
If you want my acceptance, give me a reason to accept you. If I want yours, I'll expect nothing less.
