Nobody claims Ashleys diary was fake. Ashley never denied it. No court heard claims it was fake, only that O'Keefe came into possession of it illegally ( like Maddow with Trumps tax returns but the left were happy with it then) It was like Omar marrying her brother. The only way to deal with stories like this, which every sentient being knew or suspected was true, was censorship and removal from the internet anybody brave enough to discuss the matter.
These stories made Trumps grab'em comment a non story, I mean pedophilia trumps consensual activity with adults. And Omar's incest and immigration fraud blew the democrats silly "everyone is accountable under the law" out the water.
