I used to teach anthropologist, it was my job to report back what the other culture was like. I made friends, hung out, and learned some awesome recipes.

A scientist always gives evidence and then analysis afterwards. It also helps that I can post this quickly. The left is convinced they are stopping evil and need to purify themselves of any inner evils they have. Those who want power are using various methods to convince various groups that they are A) Special and B) needed to fight this evil.

There's also the reality that many of these people have tons of power in various fields. I can't directly say they are nuts, or post without getting in trouble, so an anonymous board is quite nice.
