Why won't my parents accept that I'm gay?

I came out a couple months ago I would say probably 3 or 4 months. They freaked out for a week then they just completely started ignoring it. They avoid it so much that I don't know if they even remember. I think they love me but they are putting me through so much right now that I'm not sure. They wouldn't even let me tell anyone (I did anyway but they don't know yet) the only people who don't know is my other family members. I know it's gunna take time for them to accept it but I atleast want them to talk about it I mean I would prefer them yell and scream about it over this I mean this makes me feel like the don't care at all. I mean the only thing my mom has said about it in months is that if moving to Canada when I grow up will give me the rights that I need to be happy then do it. And that's only because I constantly bring up Canada and how I want to move there so that my mom might catch on and realize i'm just trying to bring up that I'm gay (because Canada has gay marriage) and I can't just say I'm gay to them because they will freak out and I don't want that. I mean I want them to acknoledge it but I want them to do it on there own I don't want to make them mad at me. I really don't know what to do though because I really need to talk to them about this but I don't know how. My parents aren't always the most nice people in the world I mean don't get me wrong they are very nice when they want to be but we have never really had the most open relationship. Then again I am 14 but this is more important than who I'm txting and what I'm doing this weekend so I feel like it needs to be talked about. What can I do because I don't want them to be mad but I really really need this because they are making me more confused than they already claim I am (I'm not and don't say I am I have known sense second grade so Im not). So how do I get them to talk about it or atleast to let me know that they still know about it?
