what happens if the QOP starts declaring things like BLM to be an insurrection?

There's literally no limit to the number or absurdity of specious claims; But as they are specious, they should form no part of any serious policy discussion or legal proceeding before they have even been made; And should only merit derision and immediate dismissal if made.

everything else is more important than our fears about what a bunch of loonies might possibly say at some future moment.
