Might as well boycott Modern Society.

iphones, the internet, automobiles, mass farming, and meat production, automobiles.

Your metric is so vague, and obscure, if you mean things that origated in America in the past then that cuts off a lot of things out but if you means things still currently bring produced in America there's not really much you can cut since China produces most things nowadays.

Bit childish in all honesty to "protest America" either way.
