For many years I used to donate to Wikipedia - not any more.It has become clear that it has sadly been co-opted into a propaganda tool and outright smear campaign against many reputable scientists whose professional opinions contradict 'The Science'. Many have tried to correct errors on their web pages and complain that the page mysteriously reverts to its old form. Other entries have been 'disappeared'.It is sad that it is part of the political narrative-control machine, when it started as such an altruistic idea.
