Seriously? I really shouldn't have to explain this. If you don't see any extreme or unreasonable views there, I hate to tell you this, but you're probably unreasonable and extreme yourself, without even realising it.

Just try a simple thought experiment: invert the genders or skin colours in the headlines and see how they sound.

"The Blackness Project will make you wince. Because black people can be really awful"

Does that not sound extremely racist to you?

"Why the mediocre woman's days may be numbered"

It's a statement of pure sexism. The article, in case you care, is about how much men suck. Try publishing the same article with men and women swapped around and see what your progressive Facebook friends think.

"The country is screwed, the electorate is evil, but here are nine reasons to be cheerful"

I don't think it is possible to make a more extreme statement than this. You can't go bigger than the entire country (short of going to the entire world I guess), and you can't go worse than "evil". So describing the entire voting population of an entire country as evil is pretty much the definition of extreme.

Note that thinking democracy is awful and ordinary people around you are evil has a historical correlation with murderous extremism. It's like the classical warning sign that someone may be about to do something really bad.
