Millions of people supported the Nazi's and burned jewish and Christian books with the worst of them...many justified this as being "right or good" and in keeping with the needs of the public order.
Describing millions of folks as under-taking a noxious activity(such as porn or Jewish pogroms) is simply describing reality...that millions of folks do it doesn't justify it as "right or good"!
Sure. But those actions were clearly wrong since they violated the rights of the victims. The difference is, porn harms no rights.
