Are we all left-tards here?

Come on now.  Are we?  While I myself wouldn't look for bible-thumping republicans, I think we should at least have a few moderates or radicals like libertarians ETC... 

Or is it the disproportionate european population here?

It's the disproportionate amount of free thinkers. 4chan is an alternative pornography website, which includes pedophilia and other immoral fetishes. A community like this has learned to decide what is moral for themselves, without the guide of the masses.
