RationalWiki is a noble Wiki that tries to fight against the evils of Conservapedia like Liberapedia, the EvoWiki, and to a lesser extent Uncyclopedia do, but unlike Liberapedia, it uses a special sense of humour (called "snark") instead of 100% irrefutable facts and truth. As such, RationalWiki should not be taken at face value, invoking a practice uncommon to frequenters of most wikis: sources and references should actually be checked before parrotiing anything -- anything at all.. The site was started up by former Conservapedia members who found themselves being blocked for inserting tested, substantiated and factual information.
