Well there's your problem. This belief thing is a matter of subjective opinion.
Objectively speaking, nobody has rights. The universe doesn't give a shit about our rules and self-imposed limitations.
So any rights you want, you have to make people agree within our microcosmos.
Anything beyond that is just raw violence.
No. It's not. Fascists believe the world is running a giant conspiracy against them, that they are unfairly prosecuted no matter if the evidences suggest otherwise. So by that, contrary to what you believe, they belive in the possession of an inherent right, albeit often tied to an esoterical religious or pseudo scientific reason like God or the color of your skin. They also belive you don't have, or don't deserve to the same rights because you are the conspiracy against them.
Fascists believes in fantasy. And what he is saying is an observable historical reality. Complete deferent thing. You cannot have rights if you cannot defend them. Black people would not be freed without civil war, workers would not have 8 hours work day and weekends without union. Every societal progress we had made is through force unrelenting. It is force, and sometime ultra violence, that we are able to secure our God damn rights.
