Can someone explain to me the difference between American right and left?

[Uday]

Both looks the same to your friend Uday.

I asked one friend from the engineering department who is Tea Party what the difference is, and he say that "liberals are all socialists and hate America".

I have asked a few friends in math classes what is the difference, they say "conservatives are all bigots and hate the constitution".

Both answers are obvious bias, so I looked for myself, found very interesting things.

Both parties support torture.

Both parties support violence against people who are different. Ruby Ridge is from Bush the elder, the Waco massacre is from Clinton, yes?

Both parties are keeping Guantanamo Bay open.

Both parties are giving corporations whatever they like. Even "Obamacare" is for giving insurance companies money.

There are more examples, but I think my point is clear, no? So could someone please explain this difference? Because everywhere I go, left and right is hating each other, and this makes no sense, because they look the same.
