The claim that it is only cosmopolitans or progressives who advance progress and the course of the world, which is made without any evidence and is only an expression of your own bias and preference, cannot be made in this way. You neither really know who worked on it under what conditions and with what personality, nor do you have the right to attribute to them values that you personally like.
It is precisely these unjustified attacks that in reality do not advance the world, but rather destroy it from within, because they pretend to have something, namely objective validity, but in reality they are just very personal evaluations and ideas that are imposed on others in a way that can clearly be described as arrogant and insulting. Anyone who loses people's favor in this way need not be surprised if they turn their backs on them.
