B. Robespierre attacked his fellow Frenchmen- you're comparing apples to string beans.
C. Robespieere's country was not under attack by foreign Islamofascists. D. Robespierre did not deport invading noncitizens back to their home countries WHERE THEY WOULD HAVE BELONGED, he was putting his fellow Frenchmen under the guillotine in order to remove their little heads. Get a grip.
E. Robespierre did not find his victims in corresponding about and in possession of information about poisoning water supplies, making bombs, etc. He did not find them in possession of materials designed to kill as many people as possible. He did not find them trading videos of people they had decapitated, they were not loudly confessing their intent to slaughter all infidels or proclaiming their loyalty to a religious extremist mass murderer, and so on.
F. If you're comparing the US to France you really do need to take your own advice and spend more time with your head immersed in a history book.
You left out the part about "open your mouth so you can see" :)
