I saw this video about marriage equality posted on FB. (about religion, polygamy, same sex marriage)

Aren't there other reasons for not allowing polygamy than just religious reasons? I couldn't imagine in this country of 300mil people that you might not end up having sex or even marrying your relative. Couldn't polygamy also lead to even worse overpopulation?

This person isn't wanting polygamy. If it was proposed to take the law against polygamy away, this person who is howling about same sex marriage would be howling about that perversion as well
