It is kind of interesting that owning a gun is a basic human right (according to the Bill of Rights) while marrying who you want when you want is still only technically a "privilege"
I don't think either should be restricted. I get restricting fucking RPGs, and various fully automatic weapons but you get what I mean. Also, people should be able to marry whoever they want. No matter what peoples' religious opinions are, we're supposed to have a separation of church and state.
