Of course it's not the point. It is an illustration of the point (that's why it's called an "illustration"). The point being made is that she hates evolution to the point of threating to kill people for talking about it. And you should, too.
No, the point of the illustration was the thesis of the article: Darwinism posits throw-away people, inferior people, etc.
The point was about the author’s theory of why she went on a rant: throw away people.
How you get that it was about her wanting to kill people is also how propaganda gets birthed. Quit the spin, TL. It’s obvious.
