Because brit/pol isn't just a "political forum".
It is a bastion of free speech. One of the few platforms on the internet where one can speak their mind freely and "offload" into the ether anonymously.
Weird and dysfunctional.. no problem. You can spout your schizo shit here with no consequences.

This, coupled with 4 chans unique text and image based posting system, makes brit/pol a seductive place for the depraved and mind broken. As well as for the witty and well read autistic types.
