Fair enough. The main issue with union organizing imo is that they're busy with organizing for their worker's rights (which is good!), which means they're not going to lead the charge on eg environmental issues. FWIW I think the reason the forms of protest listed on the survey are allowed is largely because they're ineffective and don't convenience those in power. Obviously I'd prefer if people went and eg camped out on the lawns of the white house, or outside supreme court justice's homes, but when that happens they get called terrorists.
