Wow, what a guy. Starts by making a death threat towards a woman he feels threatened by, continues to make physical threats all throughout the video. What a twat. Laci is just trying to help people out, she's not doing anything wrong to anyone, she doesn't deserve any of that.
Also, this uh, satitician? He's a fucking idiot. He acts like he's somehow intellectually superior, but he's missing the point, willfully rejecting concepts to suit his own agenda (pandering to a crowd afraid of social change or "political correctness") and being rather personally aggressive when simply arguing the concept would do.
0/10 would not recommend.
