I think it's important to consider that the future enforcement of these principles depends on the more righteous system being capable of defeating any less righteous system that challenges it. A principle that precludes its own perpetuation would in some sense be inconsistent.
There's also this weird dilemma that it might be beneficial to be able to make credible threats that would be clearly bad if carried out, like the old MAD doctrine.
In that one they also recommend voting for the Nordic Resistance Movement (Nordiska Motståndsrörelsen), which is an explicitly national socialist party. They have a website in english, but I won't link from here. Instead I recommend the wikipedia article that describes pretty well how charming they are. Apparently there is an ongoing effort in the US to classify them as terrorists.

Slightly leaning toward that moral progress in that area would become so cheap that people accept it.
