"The greatest dangers to liberty lurk in the insidious encroachment by men of zeal, well meaning but without understanding."
A Supreme Court Justice from 1916 - 1939, Justice Brandeis was branded "dangerous because he is incorruptible" by the FDR administration. Well, no wonder! Doing so much damage to the country outside the framework of the Constitution, Roosevelt had to stack the court to get his "agenda" through. And we have paid for that zeal without understanding since.
Now we are "lead" by a whole group of zeal without ANY understanding. Or at least without real-world experience that demonstrates understanding. Or perhaps they DO have understanding of the damages to liberty they are doing and continue on their path. THAT is the very definition of "insidious." It means to do something gradually, subtly and with harmful effect. It comes from the Latin word "insidiosus," which means "cunning." Well, THAT certainly describes what is in place now!
