It's spelled "You're"
There is no difference. You are is normally contracted to you're in speech, because English doesn't like two vowels without a consonant to separate them, and one of them gets deleted. Either you're or you are can be used; speaker's choice. The same thing applies to I'm, he's, she's, we're, and they're, among other contractions. It's just colloquial English, that's all.
You should have gone to highschool instead of jail :/
I am not even native in English.

Look at the video title imbecile.
Suppose for once that you might actually have the mentality to be able to converse effectively with me at my intelligence level.
Admit you are wrong and so is your grammar and move on. The more you fight the more fool you look like.
