Hang. Them. All.
They are unfit to live in a free society.
I don't object to hanging anti-Americans, though I think it might be worth our while to think about shipping them to Cuba. Remember the Mariel boat people of the 1980s? Why not return the favor and send Cuba our worst of the worst? We could put them in small, leaky row boats, give them compasses and maps, and tell them to row for all they're worth.
Why let them live? They are enablers of monsters.
