I have no love at all for most of the LW mods, and mostly don't go there. But I suspect that your comment was removed because it sounds unhinged and shouty, and is attempting in part to convince anyone who doesn't already agree with you through sheer force of aggressiveness, rather than just citing why you think the story you're commenting under is wrong / why you think it's misinformation. It seems like anyone who wants to have a discussion with you from the opposing point of view is probably going to experience a lot more of the same, and so nothing productive will come of it.
I don't know if removing the comment entirely would be the right move, but it's not indicative of opening a constructive dialogue on the topic with people there some of who will surely disagree with you.
