I need to lower my expectations

Words can't even begin to describe how I am feeling right now - but I will try :(
I'm angry, hurt, ashamed to give you a snapshot of the emotions.

If you haven't been living under a rock, then you are probably aware of Kevin Rudd's proclamation that he now supports same sex marriage.  It has been on the news non stop, which isn't the issue here. I think it is great that a politician is showing their support (even though I think the majority of them are idiots and most likely have a hidden agenda). Nonetheless, I'm giving Rudd the benefit of the doubt and think he is sincere with his announcement.

What is making all of these emotions stir, is the fact that I cannot believe how ignorant people are.  People I know nothing about, fine - leave them judge me. It hurts, but I can move on knowing they are shallow assholes.  When it is someone you know, someone who is supposed to love you no matter what - then that is a different story.

I was in the kitchen washing up my cup from my yummy hot chocolate I made earlier in the evening, when a news flash came on about Kevin. They were showing snippets of same sex couples publicly displaying their affection towards another.  My ever so ignorant brother screwed his face up and turned his head in disgust.

That was it, I couldn't stay silent.  "What's wrong?" I said to him, "Why are you screwing your face up like that?". I knew perfectly well why, but decided to hear him out. "Cause, two fat chicks were making out". At that moment, I wanted to throw my cup at him and knock some sense into his dumb ass head.  Instead, I replied "Would it be OK if it were two skinny girls instead?"
He goes, "Yeah"......So I called him a perv. He dug his grave even deeper by going on to state that kissing the same sex or being gay is not...wait for it! NORMAL! and he is the poster boy for perfectly fucking normal?

 I was furious by this stage, and could feel the tears getting ready to stream down my face.  I told him and my mother who was also there at the time: What is normal? Do you think that people go oh OK! Let me choose to be gay and be looked at by ignorant people like they have a disease?!
I said to my brother, you know..If you told me you were gay, I would still love you no matter what.  I'm starting to think that the feelings won't be reciprocated when I come out.

I don't care if they started to question my sexuality, I don't care if they thought I was over reacting. I clearly made them uncomfortable by my stance because they had nothing much to say after that.  I love my family but at this moment, I am ashamed of them. I wanted to believe they knew better, but clearly I didn't flick the switch that was labeled "Lower my expectations". I'm just so tired of it all :(
