No, sorry, it's not. I don't see that in the article. The leader was accused of coercing sex and having sex with a (as in one) minor[0]. Yes, that's bad, I am not trying to say it's not.
But extending what that leader allegedly did to include all members, or suggesting those members were at least fine with it, or at the very least knew about it and did nothing, is not helpful, honestly. If we did that, we would have to apply the same logic to every Catholic, as the Catholic Church enabled and hid a lot more - and in a lot more systematic fashion - abhorrent child abuse cases committed by their leaders (well, "middle-management" for the most part).
[0] The other victims he allegedly coerced were characterized as "young men", which doesn't mean they are underage.
