I'm not going to spend all day finding you more. It's easy to research. I doubt it matters how many sources I provide, but you can find whichever ones you like. There's plenty of data on it.
Like I said, I doubt it matters what evidence I provide. You'll find a way to justify your beliefs instead of adjusting them as you get new evidence. It's the typical human response. We like to act like humans are rational, but the vast majority of people the majority of the time are driven by emotion. We'd rather ignore evidence if it forces us to reconsider our views.
Beliefs do not make a person. It will not hurt to change them. You'll still be yourself. It doesn't mean anything bad that you changed your beliefs, really it only means something good. It means they you can consider new information and adjust to it, instead of ignoring it which would be bad.
Right, it would be bad if they put fuckin buzzsaws in the non crosswalk parts of roads to deter jaywalking. It would be monstrous. You however, see that and go, "those jaywalkers get what they DESERVE" because there is something broken in you that you've filled up with contrarianism and petulant nationalism.
