The fact is, who employers are _permitted_ to fire and who they _must_ fire and who must _not_ be fired is totally unprincipled in any conventional sense of that term. Empirically, it's a matter of pure power by interest groups and public sentiment, and through these things on laws imposed on businesses, and on liabilities generated; and so directly, a matter of the costs incurred on businesses through these and other avenues when they find themselves employing a given person. People who identify as "communists" and "fascists" are both incredibly tiresome but in the current world communists are politically powerful enough to live openly and impose costs on businesses that employ fascists, and fascists are not powerful enough to respond in kind. There's no way in which this can be reasonably construed as just. The question is, which is to be master--that's all. One might have expected a self-identified fascist to understand this.
