Hate group hasn't lost it's meaning because of that article and won't.
It's the responsibility of the people like Jimbo Wales, who own and operate Wikipedia, and all the other writers there to be voicing loud protest with eyebrows highly raised, over that flimsy excuse for an article and how badly it's written, not to mention how transparently the students of Prem Rawat are using the platform of Wikipedia to spread that hate group lie in a direct action to defame and libel ex-premies.
Even though that article is "just" on Wikipedia, it doesn't make it okay or legal to libel people, like me, just because they so far have gotten away with it.
