In years past, I edited numerous articles and originated a few as well. MOre recently, I have curtailed my participation in Wikipedia.
It appears partisans have permeated Wikipedia and are blitzing edits that try to maintain neutrality in topics involving race, sexuality, gender, etc. (there are two genders...period—you are born one or the other). What I am seeing is a marked shift to the left and, unsurprisingly, a corresponding loss of objectivity.
