<human>: Can you give me the gist of the text in a nutshell?

I've been with my husband for 7 years, married one year this May. My MIL is a strong right-wing conservative and I'm dead in the middle (it's seriously hard to offend me). I can carry on a conversation with someone who disagrees with me but she doesn't want to have a conversation, she wants to save my soul (even though I'm already a Christian). 

Apparently CNN stands for Communist News Network and if Jesus came back he'd watch FOX....

She believes in home-schooling children, that the woman shouldn't work, that I need to believe what she believes politically, that I'm corrupt since I was raised in the North and that I have corrupted her son.

On top of this I am 90% censored around her. No cursing (understandable if she meant actual curse words not words like "stupid" or "idiot"), no talk of anything risque, no mocking her or her beliefs, no making fun of her political heros, and no sticking up for anyone she disagrees with. 

I was called "brainwashed" because I was praising one of the laws Obama passed. 

I've begged her not to talk about politics, religion or children (which we don't have!) but every time I see her one of these three get brought up into conversation and I have to endure a lecture. 

I guess I'm asking for help on how to handle someone like this. My parents are a lot more relaxed and I can say or do whatever I want in front of them. 

I've had 7 years of this and now that we're actually married I am a ticking time bomb to go off on her (which absolutely will result in isolation from her for years).
<bot>: My MIL imposes her beliefs onto me and won't relent, even after confrontation/this is going to ruin our relationship.
