Such a facepalming concept, how the hell can boycots be illegal.
Maybe breaking a contract can be illegal, obviously sit ins, and vandalism can be illegal. But no sane person can call not buying something illegal.
Hell isn't that exactly what the capitalist class is supposedly claiming is the one thing that's supposed to guide the free market. IE we don't need regulations, companies wont drop toxic waste in your water, because that would discourage you from buying their products.
