Despite the fact that I have been out of this thread for quite some time now (at least 24 hours) and had a very nice discussion with itsthesheppy, I just wanted to chime in one last time, to correct an assumption:
The assumption that ALL OF 4CHAN IS MISOGYNIST:
4chan is divided into imageboards with a lot of variety, most of which aren't really that well-known and usually quite a nice place to be and not at all misogynist.
And then there is /b/ (gotta break rules 1 and 2).
/b/ is known for being, well, /b/.
But the misogynie many of you refer to probably stems from the "TITS OR GTFO"- posts which are usually made as a response to someone outing themselves as female.
The reason why they are made though is not misogynistic.
See, on /b/ everyone is equal and everyone is anonymous. No-one knows anything about anyone else, and yet everyone is free to interact with one another. Proclaiming yourself to be a female is usually done in several circumstances:
1. Attention whoring.
2. Trying to make your opinion seem "special" because, cleary, you must be the only woman present, which is why your female insight on the issue should be singled out and hailed as special.
In both these cases, the proclamation of one's gender is but a demand for special treatment, which goes against the principles of equality, the very foundation of the "anonymous"-structure.
So, in order to prevent this it was established, that, should a woman expect special treatment simply on the merit of her being a woman, then she should first provide a picture of her breasts with a timestamp, in the hopes that this would stop others from proclaiming themselves to be women and expecting special treatment.
Anonymous has no race
Anonymous has no gender
So trying to single yourself out, by giving yourself a race or a gender goes against the prevailing equality.
There are times of course, when you are free to give yourself a name, a race and a gender, usually when asking for advice or sharing an experience, which gives a legitimate reason to single yourself out, and I must admit, that many young "newfags" don't quite get what titsorgtfo is about in that case, which is why you will often find demands for tits in threads started by a woman for legitimate reasons (a.e. not attention-whoring), simply because many do not understand why "t or gtfo" was established in the first place and I will admit that these instances are misogynistic, and that nowadays, they are far from being scarce, but please refrain from calling 4chan or /b/ misogynistic without giving further details or examples.
