I mean yeah isn't that kind of the point? You have some uncompromising principles, say someone asks you to cast them aside? It's not gonna be easy to do so most people choose the second best option and live with the cognitive dissonance. Either that or prefer to do as you say. Far as I understand United States and many other countries were founded because of that.
Another example. Look at my country. Hailed through years as the socialist paradise. Same governing leftists sent it to shit. Now what people do? Easy, engage in simple denial, anger and cognitive dissonance about it. "It couldnt have been real socialism", "it's not as bad as they say in the news", "news must be fake", "clearly it's someone else's fault it went to shit", "oh oh maybe it was corruption" and so on and so forth.
It's not as weird of an attitude and it is kind of part of humanity at this point.
Look at my country. Hailed through years as the socialist paradise. Same governing leftists sent it to shit.
Tells me that it probably was corruption. You got a bad group of leaders, and what had been good went sour. Unfortunately, that's the way shit goes; bad leaders can wreck a great thing.
I mean tbf, the number of socialist countries that even tried to actually be a little bit socialist can be counted on one hand. It may not have been a great place to begin with.
I think that's a problem, yeah. The people that are ideologues aren't the people that tend to lead battles and win revolutions, and the people that win revolutions don't tend to be ideologues that willingly give up power.
