Personally at this point I'm looking at it even more generally: anybody whose Morality is such that they're OK with the mass murdering of children in Gaza by Zionist for the "crime" of being Palestinian (the list of just babies 1 year old or younger killed by the Israelis just in the first 3 months of the Genocide is 17 pages long) isn't going to Morally be above "merelly" using little children for sexual pleasure or more broadly the use of violence to force other human beings to do what you want that's the core of Fascist thinking, especially the Nazi kind.
I guess what I'm trying to say is that somebody who justifies and supports any one form of extreme Evil is going to at the very least be uncaring in the face of other forms of extreme Evil.
