I have seen this said about Thiel hundreds of times, and it's just not true. He said that from a strictly Libertarian perspective - from the perspective of political freedom - things 'went downhill' when women got the vote because women tend to more consistently vote in favour of social programs and thereby in favor of expanding the state and decreasing personal liberties, once those programs get introduced via legislation. Therefore, he doesn't suggest to not let women vote, as Gawkers "suggests", he just states his conviction that times are difficult for libertarians.
Also, having written a book precisely about the difference between statements being offensive and just being perceived as offensive by PC culture, all this must make Thiel shake his head about the reading comprehension of the general public.
