It's of course one of the most messed up things to read, but it's a common thought process of people influenced by propaganda from those countries regimes, or are actively spreading propaganda: the framing of "so called western countries/first world countries/etc" is the first red flag.
And then of course the angle is that western countries are decadent and are denying traditional values. This is a common thread of the Russian regime propaganda for example... Because when the regine destroyed everything else, with no prospects of a good future, it's traditional misery that has to make up for the rest.
So to sum it up, OP is actually making a case for the false traditional values of the regimes from the most corrupt and broken societies - where sex trafficking and marrying underaged children is part of the status quo, because it's "traditional ".
Somehow this propaganda works with some people in the west lol
My most charitable interpretation is that you are justifying such sexual abuse of children.
But don’t get too excited yet (pun intended), in many parts of Russia or the Muslim world getting caught sexually abusing a child will make you wish for jail.
