Alpine Linux Diskless Mode (opens in new tab)

I never noticed any politricks while using it :-)

You could say that supporting Open Source is a strong moral, ethical, and perhaps political position. The same could be said for someone's position on Fascism.

That being said, is there something there beyond the one statement in the homepage headline?

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.
