It is a cross-posting extravaganza. (Many thanks Intransigentia) But no, really, if you ever need to explain to your friends about Patriarchy or white male privilege or hetronormativitiy or any of the diverse topics along those lines, these two posts are not bad places to start.
The first is a post from Shakesville. It is long for a blog post but well worth the read. Check out the article here.
The second is a post from the Pursuit of Harpyness, it is a personal anecdote, but a good look into the hetronormative standards which pervade our society. The comment section is also quite informative for this article. Find it here.
