I loved this post on Christian privilege and marriage equality by Mike Gillis. It’s a very succinct explanation of the problem with religious arguments against civil recognition of same gender marriages: i.e., limiting the rights of others based on the tenets of one faith (really one interpretation of a faith out of many, in this case) unjustly privileges that faith and its members over all other members of society. And as Gillis notes, Christians who believe their religious opposition to marriage equality should be enshrined as law are also discriminating against other Christians who support marriage equality – insisting that only their interpretation of Christianity can be the basis of general laws. That’s some kind of privilege.
If your religious beliefs condemn marriage between two people of the same gender, then you shouldn’t marry people of the same gender. While you have the freedom to limit your own behavior in matters of sexuality, diet or religious observance, you don’t have any power to limit the rights of other people, particularly those in other religions or with no religion.
If someone else is allowed to marry their same-sex partner, the anti-gay marriage advocate is affected in no way, oppressed in no way, their right to hold those beliefs is violated in no way.
Just as orthodox Jews aren’t victims of oppression when other people are allowed to legally watch television and use electric appliances on Saturday. Just as Muslims aren’t victims of oppression when other people are allowed to legally purchase alcohol. Just as Hindus aren’t victims of oppression when other people are legally allowed to eat beef.
You are expecting a level of cultural dominance that is completely unreasonable. You are expecting the right to to demand that your religious practices be taken as civil law and that the prohibitions of (I assume) Christianity be enforced on everybody — including non-Christians and Christians of denominations that accept equality in gay rights.
