If you know about the USSR only from the words of a nostalgic grandmother, it is better to be silent.
For "disrespectfulness" to a high-ranking official or party functionary, they could well be fired and jailed on a fictional occasion. The question is in the depth of insult and misunderstanding.
However, soon you will feel it on your own skin - only instead of the CPSU will be the EP, and possibly the RPC.

The realities of the Soviet Union you know only from the opus of Woslansky and the sewing of the reconstructional "Fire", so turn off the organcher in your head. It is full of examples of how a simple "small" person successfully confronted the party and civil servants at that time - pick up the archives of criminal cases for the period of the 50s and 70s or read special periodicals. And from my own experience, I could tell you how in the late 1970s, we, several yesterday’s graduates of Baumanka, successfully had a relationship with the secretary of the first-person partnership committee and the chairman of the trade committee of one large industrial enterprise due to, say so, the inappropriate use of these two production capacities. And what would be the consequences if in your capitalist Rash a 22-year-old "young specialist" would say the word to the owner of the enterprise or someone from the management? The question is rhetorical. So don’t cheat here with your hassle of book knowledge. I began to experience repression for disrespectfulness to the superiors precisely with the arrival in the country of freedom and democracy, and not in the USSR at all.
