I can't say for sure. What I said is that they seem that way to me, and are within the range of what one expects from divisive and emotional topics. That isn't proof (which is elusive if not impossible in any case), but is at least based on many years and god knows how many lost hours poring over this sort of data.
Incidentally, I was talking about downvotes and flags from every side of the conflict, not just the side you're talking about. I don't see a lot of difference there either.
