Think about it, love is love. Gender doesn't have much to do with it. While marriage is based in religion, and religion is heavily biased against gay people, this isn't even religious-type marriage. It's "I die and you get the house" marriage. Plus, it makes the relationship more official. Why does it bother anyone if gay people get married?
I just find it hard to believe that in today's modern age there can still be people basing their thoughts and beliefs off religion. It made sense in the 1500s when they didn't have science and they needed to believe that all their hard work trying to survive would pay off somehow after they died. Plus it gave them something to live for. Think about it, if religion wasn't so widely believed, it would seem as likely of being true as a fairy tail. Plus, it interferes with the real world way too much. I wouldn't mind it if people left it in their churches because then it wouldn't be a problem. But no, instead people take it with them everywhere, causing tons of problems outside, in the real world. This might cause something as small as a minor conflict or argument in public. But it causes problems as big as Proposition 8 or in extreme cases, wars.
Dedicated religious people are some of the worst people out there. You'd think that someone who spent a lot of time on a religion was a friendly, good person. That isn't the case though. The dedicated-religious people can't stand people living their own lives. They won't let people live without their burden. It doesn't matter how silent you keep it, they simply aren't OK with people living peaceful lives. This brings us back to Proposition 8.
What about gay people bothers them personally? It's just so immature, I can't believe that these are grown adults doing this. Are gay people brainwashing children into believing thousand-year old fairy tails? Are they teaching people to make life hell for people who aren't gay? Do they walk around trying to turn other people gay? Maybe some do, but I haven't heard of that happening. As far as I'm concerned, people being gay or getting married to people of the same gender doesn't concern the religious at all, nor does it interfere with them or their lives. In a way, religion is just another example of how we (as a species) are not done developing. Yes, it served it's purpose thousands of years ago when people needed it to get through the day. It has no purpose anymore. When was the last time any religion did anything other than bother people? That's all it is, all religions are doing anymore is either bothering people or sitting there without doing anything.
By the way, I'm not an atheist. I do believe there is a God, or some kind of higher-being. I just can't see the world without one. However, I don't follow any religion because they all seem to be corrupt, and none of them have yet to show any signs of being true or right, I have no reason to follow any.
