It’s so frustrating. You catch them outright lying, and they just move on to the next lie.
Well, that's your problem. There's no need to correct all errors, lies and etc. on the forum - people will generally figure out the details that matter, even faced with posts that misrepresent the source material.
By now, on this issue, the forum is pretty well in tune with the dozen or so who have comprehension problems, or who are taking the opportunity to entertain themselves.
