This request should just how ignorant you are.  

it appears that if you required posts to be backed by a verifiable source.  You should then produce a list of sources that are acceptable.  That would be much easier for you to do than a list of unacceptable ones.  As we all know lie after lie has been published by even the main stream media.

So from this day on, post must not link to any source until it is approved by you.

I have just one question for you, which step from the book of Marxism is this?
