Yes I have - in that they support the migration of muslims and cultures that do that in general, bringing in the rape of young girls to the west
There are a lot of reasons (or possible reasons) behind that agenda of pushing Muslims into the West, mainly Europe: Provoking conflicts and tensions between the Muslims and the westerners, especially gays and feminists (look up negative dialectics, they don't support all those contradictory things simultaneously for no reason), lowering racial and cultural cohesion levels, clearing out some parts of the Middle East so that Israel can expand, and so on. Popularizing child or even teenage marriages sure as well isn't one of them.
Concluding that the elites are pro "pedophilia" as in "marrying girls young" (be it to older guys or guys or boys their age, whatever) because they support Islamic mass immigration into the west would be like concluding that the elites are against gays because Islam is, when we can clearly see the insanely strong gay agenda going on in the west (just as we can see the anti child marriage feminist agenda, for instance). Like I said, they are adepts of the negative dialectics school, they want to intentionally create conflict.
But I can guarantee you that feminism is one of their strongest tools and if girls get married before they're old enough to become used-up sluts, feminism would diminish VASTLY. Never forget that
it was feminists that implemented unreasonable high AoC laws throughout the whole west, as well as other shit like female sexual liberation, no fault divorce and so on.
They only support promiscuous, degenerate pedophilia, mainly homosexual man-on-boy pedophilia (and even this one they have to support discreetly, so that people won't freak out too much), they don't support young marriages. Because young marriages would create less degeneration, not more.
