::Nobody has accused you of being libellous that I've seen, nor have they called you a liar. The reason that you were cautioned about your behaviour on the Anita Sarkeesian talkpage is that you were using the space, not to propose improvements to the page, but to criticise the person that it's about. Wikipedia takes this very seriously because the whole site can be found responsible for things that editors like you and I say, even if it's not in article space. For this reason, biographies of living people are taken very seriously, and come under the most scrutiny of any Wikipedia articles. Here is the appropriate policy, it's vital that you read it if you want to edit articles about living people.

With regard to the Anita Sarkeesian article, if there are specific additions that you want to make to it, please suggest those on the talkpage. "She's a liar" is insufficient, you need to find a notable source whose content you want to add. This policy details how we determine what sources are notable.

At the end of the day, though, whatever you believe, Wikipedia is going to describe the positions and opinions of a lot of people you disagree with. That doesn't mean that Wikipedia endorses those points of view, simply that they are notable people whose statements and actions are worth documenting here. At least until you get a bit of experience, I strongly recommend you stick to uncontroversial topics, or BLPs of people whom you agree with.  

You must clearly be blind take a second look at the very top of this page and you'll see a link to libel on it. Its even in t≈he very first sentence, please inform me if that was too complex for you to understand? hell I qoute it for you since this is obviously to complex. Also answer the question I asked stop writing on my talk page.
