I've had several arguments with her about the way we think.

She believes it's okay to steal, kill, do drugs, and make others life's miserable.
I don't think this is right. You should never steal and it's not okay to kill.

I just wanna slap her sometimes, cause she goes off on me telling me I'm stupid cause i don't like to steal. She encourages my brothers to steal and when the cops come to the door she says they wouldn't do such a thing.

I hate her with a passion. It is not okay to steal and it is not okay to make someone else feel like crap, especially mine cause I'm her child. I can't wait till I'm old enough to move out and if i decide to adopt kids I will love them, but it wont be okay to steal or do harm to others.

That sucks man.  I'm sorry your mom is like that.  Not much I can offer I guess, but hang in there bro.

I'm sorry your mother isn't living a good life or setting a good example, but I give kudos to you for being courageous enough to stand against it.

I hope your mother hasn't actually killed anyone and it was just a figure of speech, maybe you feel she is capable of such a thing? Idk.

Stealing and lying is pretty low though, and she will probably end up in jail soon enough.
Continue to keep the faith and hold your head up high, because you're certainly an example of someone who is set on breaking the cycle of abuse. 

Shes never killed anyone and she doenst steal but she thinks its okay. If my brother takes my crap, hits me its okay.
He shot out the neighbors truck and shot at there window cause he was angry that they called the cops on him and a few days later he beat a kid up. He's even shot me with his bb gun on purpose.

My mom said it was okay. The thing is my brother is constantly making me feel like crap he's only 12 but if i say hows ur day he gos off about how im a bitch for inquiring about his day or he'll hit me. I can't do anything cause im almost 17.

My mom also goes off when i tell her shes not being a good parent. I dont know what is like to have a parent at all. I've never been asked how my day was at school and when i tried to tell her she told me she didnt give a ->-bleeped-<-. I've never been punished for anything. We are rewarded when we do bad things. When I first decided to live as male and to embrace who I was I was only 10years old.
I was extremely suicidal and every day my family would tell me to just go ahead and do it. Everyone in my family says I dont know how to cope with things but I think I've been copeing farely well. I'm still here for how long, who knows. I havent thought to hard about it for about a month but I still have the rope and a support structure and sometimes it seems like none of this is worth living.

Why go through hell for nothing if I dont have to? Why keep going? What's the point, honestly? To live to see 25 or 50 so what, does any of this really matter? What if this is all a nightmare and all I have to do is do "it" and I wake up and everything is fine?

Live through the nightmare then get revenge by being successful where she was not.

Kat got it in one. The best revenge is to live a better life than them.  At 17 you are nearly at the point where you can move out, and live the moral life you so obviously want and need.  Twenty or thirty years down the track, when you have a loving family , and are successful in you chosen career, they will realise just how wrong they were.
