I have grave reservations about supporting an organization that is, essentially, becoming a for-profit charity, with more than a third of their income going for advertising, and a substantial amount going to pay lavish salaries for the founder and members of his family.

Violence is an ugly thing, but not the ugliest of things. The decayed and degraded state of moral and valorous feeling which believes that nothing is worth violence is much worse. Those who have nothing for which they are willing to fight; nothing they care about more than their own personal safety; are miserable creatures who have no chance of being free, unless made and kept so by the exertions of those better than themselves.
