If gay marriage should be legal, should polygamy also be legal?
Marriage between any number of consenting adults, of any sexual orientations, should be legal. There's no reason any form of marriage between consenting adults should be illegal.
If there argument is everyone should be able to get married then a pedophile should b able to marry a 6 year old
both are immoral so might as well do both if your doing it. Let us legalize child molestation while we're at it (sarcasm).
