If you are calling my father a useful idiot, you might imagine my attitude if you stood in front of me.
Shouldn’t you be stamping your feet while you say that?
Even though I have known an lot of Jewish people in my life, I rather doubt if I know your father - probably I never met him, never talked with him, never saw anything he wrote - so I can't make a judgment on that.
Besides, it was Lenin who coined that phrase and made that judgment about a certain mindset of people. Those were the leftist radicals who willingly or perhaps unknowingly supported him and the advancement of Communism and the Soviet state for their own idealistic and mistaken ends. But their efforts helped put the real Communists in power - after which they were more than happy to eliminate them as a potential threat.
You know your father, I don't. You put the shoe on him if it fits. If it doesn't, I'm OK with that.
On the other hand, I doubt if I know you, either. But I have seen plenty of what you have written and I know a lot of other people who seem to think the way you do and their efforts (if successful) tend towards an ultimate totalitarian system which is precisely what Communism and National Socialism is all about (Islam too, but that might be another discussion). In my opinion, the shoe might fit pretty well on you just as it does on them. You may wear it proudly or uncomfortably - your choice.
But if it doesn't, you sure have a lot of convincing to do on this forum.
