Most overrated and underrated political philosophers?

[Storebought]

I made the mistake of reading about Foucault & his views on the age of consent....

Yeeees... you see, I was not exaggerating when I mentioned 'extremely distasteful politics and moral attitudes'.

I actually don't understand the objection.

Foucault's arguments (as they were oversimplified on Wiki...) on how 19th century criminal law was based on a 19th century medical science that transformed every sexual activity that wasn't vaginal coitus into a "disease" is well known. Commonplace, really.
