In many cases, I think so. People everywhere get their morality from culture. Since many people are raised conservative, and risk damaging their social connection in their community by straying from conservative values, people can be very protective of certain social conventions and perspectives, out of fear of social isolation or even alienating themselves from their actual nature in order to adhere to social convention.

Its an understatement to say that the far right/fascism weaponizes this fact. But many many conservatives are workers which means that they share lived exploitation with the rest of us. Capitalism is the force that divides the working class, and when we participate in divisive/sectarian tendencies then whatever ideology we claim, leftist or whatever, then we are carrying water for the billionaire class.

Its not always that simple though. Many people experience real trauma by having conservative values thrust upon them. Objective morality is a plague, but so is dualism. We need to think completely differently and work with others to navigate these dynamics
