The issue with the radicals, is that could be taken as conspiracy to murder, if they really were concretely shown to preach it.
Plus, isn’t pogrom a violation of 1st Amendment Rights for someone else anyways.
It is not a violation of the 1st since it’s completely voluntary. No one has to accept the benefits of a 501(c)(3) organization.
All this anger is more than justified but misplaced. You should be angry with Congress. They are 100% responsible for the tax law. The tax law is an abomination and a scandal. And year after year they do noting but make it worse.
