Individuals have the right to choose to stop buying from a company for any reason they want

According to a quick reading of some stuff here:http://www.bxa.doc.gov/antiboycottcompliance/oacrequirements.html there is legislation penalizing US citizens or corporations for participating in unsanctioned (by Uncle Sam) boycotts led by foreign governments and requiring reporting to the US of requests to honor such a boycott.

Scary stuff.
