One can reasonably talk about free trade among the 50 states of the US. But there has been and is nothing free about trade among nations.
What is being promoted now is a kind of labor arbitrage for the benefit of certain economic interests but to the detriment of others. There is nothing free in this current arrangement. It is a political and policy calculation. There can be other policies. To call what we have now free and the imposition of a textiles tariff unfree is silly.
