No, I did not say that. I am not even talking about what they should or shouldn't be. There's no set rule which says engineers are supposed to be pro-authoritarians or anti-authoritarians.
I was disagreeing with what the parent said: "Engineers are supposed to be anti-authoritarians."
I take that to mean that the person thinks engineers are anti-authoritarians - which is simply false and not what happens in real life. Engineers are often enablers of authoritarians.
And this is a bad thing but just fact of life. Humans are flawed and greedy for power. There are higher chances of someone with power to abuse it (engineer in this example but could apply to others too).
