If all of my other posts fail to convince you of anything, I hope this one rings true:
LIFE IS SHORT.
In my opinion, life is too short for unnecessary unhappiness!
I have thought occasionally about seeing the other side of things, that, well, maybe marriage really is just a bond that should occur between a man and a woman. But then I think:
Why should I devastate families and loved ones for the sake of a title?
Why should I deny a lifetime of happiness to a people who need it just to give me a moment of satisfaction, if even that?
Basically, life is too short for us to infringe on other people's happiness. In the grand scheme of things, we are so small and insignificant. Our lives only last 80ish years. Why should that small amount of time be depressing for anyone?
No one deserves that.
No one should have to be miserable for the small amount of time we have.
So I urge you to make the choice to grant people their right to marry, which, though it may be against your principles, will give someone a lifetime of happiness.
