Straight couples: you are no better than gays. Your relationship is no more and no less important. We are all humans. So get over it.
It doesn't affect your life. Ever. Your hatred and intolerance does affect them though. You are denying other HUMAN BEINGS their rights. You are creating animosity and negativity when you spew your narrow minded views. Whether religious or just "eww gross". You don't have to agree with them. But don't deny them of their right to equality. Don't create any bigger of a divide between people of this country.
You aren't living their life, so you have no right to deny them the ability to live life as an equal.
