In the NT, Slavery is broadly condemned.

[Clare73]

That remains your own interpretation. It never limits to man stealers. It is just as literal as slave traders, though the word itself has the two fold meaning of kidnappers and slave dealers.

Strong:
from a derivative of a compound of <G435> (aner) and <G4228> (pous); an enslaver (as bringing men to his feet) :- men-stealer.

The primary meaning of word is actually more in favor of an enslaver (by bringing men to his feet). So the verse literally condemns enslaving itself.

The compound of a word does not mean it is the specific meaning of the word.
Strong's concludes the meaning is men-stealer, not slave trader.

Likewise, you have set Scripture against itself in Eph 6:5, Col 3:22, 1 Tim 6:1, Tit 2:9, 1 Pe 2:19.
