A disagreement about a position is not a lie.
If someone feels that the arguments that someone has made indicate a certain frame of reference that they are coming from, that does not mean that they have admitted that that is where they are coming from.
We used to have scientific racists on this board, who would go on and on about “factual information” that they would use in an attempt to prove the inferiority of other ethnic groups. If you called them a racist, they would call you a liar, and demand to proof that they said racist things, all they are doing is pointing out facts.
So, yeah, if there was someone who was pointing out facts in a way that would indicate that they were trying to make some sort of point, there is the possibility that some posters may get the impression that that poster was trying to make some sort of point, and call them on the point that it seemed they were trying to make.
That the poster in question didn’t admit that they had any reason for interjecting these facts, and had no point at all that they were trying to make doesn’t mean that those who assumed that poster had a point was lying, it just means that the poster was making worthless contributions, for no reason at all.
You would have to understand the confusion of other posters thinking that the poster in question actually had a reason to be posting.
In that case, it would probably be worthwhile pointing out where they had made such preferences known. Would you be needing them to specifically admit that they had a sexual preference for young boys, or would the factual information they offer about how NAMBLA has some good points and intentions be enough?
