GH > I’ll not venture to speculate which party ranks higher on the arrogance/hypocrisy meter on any given day.
Human nature is the same on both sides. But, when one side tends to change things and decide for others, and the other prefers the old ways and advocates less concentrated power, then yetzer hara would exhibit itself in a different ways.
There is more room for lying and arrogance when a navi sheker is proposing to save the world and offer people new solutions: workers will run the factories, government will print money for you, etc.
Traditionalists get into intellectual holes when they advocate things that clearly need to be changed – slavery, not studying professions, rejecting masks/vaccines – but this is a much smaller field.
