/r/purplepilldebate is pretty interesting and hilarious; it's a delicious mix of clashing ideologies involving dating, sex, gender roles, and so forth. if you read people's arguments from a detached perspective, you'll come to the realization that men really are the more logical and "ordered" sex, while women are the more emotional and "chaotic" sex. one is not better than the other, but the two sexes do think in completely different ways, and, until the rise of feminism in the last century, the two complemented each other nicely; this is what made our western civilization so great and successful.
it's also an amazing study in Internet tribalism of the highest order. sure, on flag boards like here and /pol/, you have people who generalize flags as being a certain way or another, but, aside from proxyfags, you have no control over your flag, it's based on your IP address. on reddit, subreddits can allow you to tag yourself with flair, leading to literal red-team/blue-team scenarios like that on /r/purplepilldebate. this means that if you hang out there long enough, you'll start to "identify" with one side or the other, and then you'll start to dismiss people's posts out of hand without reading them, solely because they have the Wrong Pill Color by their username. this leads to an endless spiral of in-group/out-group dynamics, and in the end, nobody posting there learns anything. however, from a detached outside perspective, there is an absolute wealth of information to be found, especially if you grew up as a beta nerd who never naturally learned how to socialize with the opposite sex.
it also makes you truly appreciate the anonymity, specifically the lack of usernames and user-flair, here on 4chan
