The most fundamental feature of Fascism is that it divides people. It elevates certain people at the expense of others. If the people who are being denigrated are wiped out, fascism selects a new subsection from the previous elevated demographic.

This undermines cooperation, collaboration, and trust.

“If the fascists would just work together” is quite a predicate.

It’s like saying, if only the water could be dry… then you wouldn’t have a problem.
