It seems a lot less political than the codes of conduct that most large FOSS projects have. Its also not specific to any particular culture as those often are. Its not taking a stance on any specific issue such as those you mentioned.
Its just saying "anti-fascist" which is a pretty uncontroversial thing to say. I am pretty sure the vast majority of people are opposed to fascism.
The problem is that "anti-fascist" has been co-opted by Antifa [1] which have been designated as a terrorist organisation [2].
I think if it was "anti-communist"/"anti-marxist" it would be equally not appropriate for an OS.

Looking at current day politics of most western countries, I'm not so sure about that anymore. Most people are only opposed to being labeled as such while supporting fascist politics
