I didn't really notice it but you're right, caring about "human trafficking" seems to considered a "right wing" thing now. Similar to how freedom of speech was dumped by the left and is now considered a right wing idea.
Consider "The Sound of Freedom", the "right wing conspiracy theory" movie
Consider the human trafficking of underaged sex slaves from Mexico to the US both via legal and illegal immigration
Consider Eliza Bleu, the "right wing" "human trafficking survivor" who appeared on Timcast and then quickly disappeared because she's a narcissistic grifter liar.
So why is human trafficking right-coded?
Is it because by addressing right wing concerns about human trafficking the left would have to concede that the right is right on some issues?
Is it because by address human trafficking, the left has to admit the immigration ideal isn't as great and spotless as they want it to be?
Or is it non-political: some women are such degenerate self-disrespecting self-objectifying whores that want to make money from their body so much that they consider "human trafficking" a necessary evil? Or by addressing the issue, they might hurt their ability to make money in this "industry"?
