"Gays are oppressing me by wanting marriage equality. I have a right to say I don't want them to marry" - Paraphrased from a few comments today.
If one group wants the right to do something you don't agree with that doesn't effect you, breaks no laws and has no net effect other than allowing adults to live their life as they please without harming or infringing the rights of others, Then IN NO WAY are your rights being challenged nor your religious beliefs being taken away from you.
You have the right to say "I don't agree with this" and that's that. You do not have any right or expectation to have other people being forced to live their lives or be denied rights according to how you have chosen to view the world.
Timmy and Johnny want to get married. This does not mean your church will close, it does not mean you have to like the fact they are getting married, it does not mean your opinion has to change. It does not mean your children won't grow up to be as straight as they were ever going to be.
It means Timmy and Johnny want to get married. That's it. That's all.
Timmy and Johnny are not demanding your marriage end. They are not lobbying against your right to get married. They are not seeking to change your life ONE LITTLE BIT.
Lobbying for rights and/or services to be made available to EVERYONE is not oppressing ANYONE.
Demanding rights and/or services be taken away from a group of people based on their sexual preference, race or chosen flavour (or lack of) a god is oppression and discrimination.
Arguing against anyone else to be allowed something you have now and won't be taken away from you is utterly ridiculous.
So opponents of marriage equality, playing the "I'm being oppressed"/"My rights are being taken away"/"My religious freedom is being squashed." cards are simply knee jerk reactions with no logical premise behind them.
Lose some sleep over gays getting married if you must but I will point out, regardless of a ring on a finger or lack of, they're nailing each other anyway..
And remember this:
Your way of life is not under threat. No one is trying to take anything away from you. No one wants you to do anything other than stop oppressing people who do not fit into your idea of gender dynamics.
