Jason Wakefield has a fantastic article in the latest issue of New Humanist magazine about the arguments against gay marriage and why they’re all wrong. It may not be anything you haven’t heard before, but it’s always nice to have an easy reference to send to conservative Christians/homophobes:
2. “We must preserve traditional marriage.”
Given that marriage has always changed to suit the culture of the time and place, I would refrain from ever calling it “traditional”. If marriage was truly traditional, interracial couples would not be allowed to wed, one could marry a child, ceremonies would be arranged by parents to share familial wealth and the Church of England would still be under the authority of the Pope.
12. “Why is it so important for gay people to have marriage?”
For the same reason it is important to straight people. Our relationships are just as loving and valid as heterosexual relationships, but our current marriage laws suggest it is not. We are equally human and we should be treated by the law as such.
There are more arguments against marriage equality than the ones Wakefield mentions but they all have simple rebuttals. There’s not a single good reason to prevent same-sex marriage. It’s all plain, simple, almost-entirely-religion-based bigotry.
