I'm Tim Post, a community manager for Stack Exchange, I'd like to respond to this and appreciate you bringing it up.
No one gets to infect a site with rants of any kind, Nazi or otherwise. Similarly, one doesn't have the right to proselytize their political views, religion, phobias or hate in a manner that disrupts the purpose of the site. That falls under our golden rule of basically not being a jerk. If your behavior, however passive is causing a disruption, that behavior needs to stop.
I've examined this user's profile at least a dozen times, reading it from beginning to end as many. For the sake of discussion, let's ignore the fact that the person that wrote this profile indicated that they were 13 years old. On the Internet, no one knows that ... well, you get the gist.
Please read the rest in its entirety before reacting.
The first set of questions I asked was, what does this profile not do?
It does not use profanity or vulgarity, though many will associate certain words it contains with vulgar people or ideas.
It does not directly attack any individual based on on their religion, race, ethnicity, sexual orientation or anything else. It does, however state that certain religions are inferior. While he may have insulted the institution of several religions, he's not directly insulting anyone for simply belonging to them.
- It no longer displays a swastika.
I'm putting my personal beliefs and feelings aside while writing this, as a Stack Exchange community manager it is my job to be completely objective in such evaluations, even at the cost of being wildly unpopular for doing so. This was a difficult decision to make.
At the end of the day, it's the reception of the text that creates needless angst and disruptions within the community. This isn't the first time we've been contacted regarding the text and we only alter a user's profile when we feel that interceding is absolutely necessary. Any technicality one could raise does not alter the fact that the intent of the writing was to be deliberately hurtful or hateful, even just from the vantage point of the offended.
Note, not all of the text was removed, only the portion that I found to be the most egregious and deliberately offensive to people of certain religions.
