When you start talking about "always", you're going to need to apply way more rigor. Conservatism is a political philosophy that emerged in reaction to the emergence of liberalism in the age of European enlightenment. Conservatism champions the idea that order tends towards chaos, that order is required for society to function and that chaos destroys everything, that some individuals are more worthy than others by virtue of their birth and hierarchical position, etc. In the 1700s, Tories we're conservative.

But what we call conservatives in the USA are liberals, and they always have been. Liberal philosophy posits that individual liberty is more important than strict hierarchical order, that society should be organized to limit the power of the state over individual freedoms, etc. Capitalism and market systems are liberal constructions.

Liberalism, however, is still historically situated and emerges during the age of discovery. As such, it is not a moral movement but rather an political one. Specifically, it emerged as the merchant class needed a way to undermine the authority of the nobility. Liberalism birthed all of the bourgeois revolutions across Europe and European holdings. Every tri-color flag came out of this movement. But liberalism couldn't undermine the entirety of merchant dominance, which means it had to be compatible with slavery, misogyny, racism, genocide, and settler colonialism.

This, liberal philosophers struggled with systems of science and systems of morality that allowed for these things to occur. Race science is a liberal cobstruct. Eugenics is a liberal construct. The belief that black people aren't fully human is a liberal construct. The idea that white people must civilize the savages is a liberal construct. The Berlin Conference, the professional police force, the state police force, all liberal constructs.

When Haiti was liberated through the successful slave revolt, it was the French monarchy that determined every single person on Haiti that was a newly freed slaves represented a loss of wealth for French slave holders, and they levied a debt on Haiti to recoup the cost of freedom. The liberal capitalist world acknowledged the debt and required Haiti acknowledge it in order to be recognized. This is a liberal financial construction the remains in the hands of liberal democracies to this day, draining Haiti of it's wealth.

The Nazis, are not Conservatives. They are Liberals. Fascism arises from liberal democracies. It uses specific liberal systems to grow and develop. It is essentially the violence of liberal capitalism turned against liberal capitalists. Prior to the rise of European fascism, the things we attribute to the Nazis are just things that the Europeans had been doing to brown and black people all over the world. There's a reason the Third Reich studied US settler colonialism systems and industrialized them. There's a reason why US capitalists, liberals of the highest order who believed in the individual right to private property and access to free markets, supported the Third Reich.

You can't just go around saying everything bad is conservative and everything good is liberal/progressive. It's a dogmatic approach to political and historical analysis. Nothing could be further from the truth. Liberalism was a progressive step from mysticism. Conservatism was a reaction to liberalism. And most the ills of the modern era are traceable to liberal philosophy, not conservative. In the USA, we redefined conservative to mean liberal and we redefined liberal to mean liberal progressive. Maintenance of market systems is a liberal project. Maintenance of representative democracy is a liberal project. Eugenics was a liberal project and the US engaged in it through the 1970s and we still have after effects of race science in our discourse. All liberal.
