I was also an Engineer with a wide and solid foundation in the physical sciences, so objective observation came early and easily.
From that point on, I easily concluded that the problem was Communism per se, not "Russians".
Further investigation (History) revealed that The Marx (unworkable) Economic Philosophy of Communism was weaponized in Western Europe (primarily France, England and Germany) and sent to Russia to compromise Russian military strength and population advantage.
In short, Communism was used as a weapon of mass destruction against Russians to prevent Russia from being the deciding factor in the outcome of constant European wars.
It didn't take long after figuring that out to deduce that Russians themselves were just normal people like everybody else.
It might be worth noting that Russians did not have the opportunity to inform themselves about Communism because there was no track record of it in 1917, and Lenin sold 'em out. No other Communist group can claim the facts weren't there, and no other Communist group has effectively ended Communist rule.
Russians? They're just like everybody else except for one thing, they pretty much got rid of Communism.
You are spot on. I grew up in the 80s and had no love for the Soviet Union or Communism.
Fortunately, the Soviet Union is no more and I wish the Russian people the very best.
