Do you think privilege (white or otherwise) is being used to silence and undermine any opinions or viewpoints in this case?

To be fair, a sound argument also may be used to silence and undermine opinions/viewpoints.

I'll point out that when the NZG massive has been in full swing (i.e. three people with the same opinion posting at the same time), belittlement has been an accepted tool for silencing opinion. So it's not like we have some high standard of discourse here all of a sudden.
