First of all, as long as two adults, both free to do as they please decide to have a relationship, I am not going to pretend it's something like slavery. Maybe I am morally against it. But that doesn't change the fact they are consenting adults.

The other is, would you say the same about for example American men looking for younger wives in places like Thailand or South America? Let me guess, in that case it's also the evil women preying on men.

Third, the thing you posted said NOTHING about older women and younger men.
Even if they did, my first point still stands. Consenting adults. If I say this is sex trafficking, then it opens the door to calling people like Leonardo DiCaprio a sex trafficker as well and such, which is frankly, retarded feminazi fantasy.
