I personally have no objection to it. If two people love each other enough, then I say let em fuck with rings on their fingers. My cousin is gay and I have several gay friends. Even if I didn't I still would have no objection to it. It's how I raised myself. My parents are old enough to have the "old generation" kick in them towards many issues and they tried to pass that on to me like so many have done to sooo many of people like you.
This thread was mainly stimulated by the new 'rule' in force saying that they can't use religion in the fight against gay marriage. I urge you to do the same here. I want to hear some honest to the bone answers about why you do, or mainly don't, agree with gay marriage with those reasons not having to do with religion.
