I think I start to see where the problem might have arisen. Let's focus back into the "individuals" inside Nazis and forget about whether "Fascism" as an ideology is respecting selfs.

Hitler is a self-conscious individual who did a lot of thinkings himself and thus cannot be described as "selfless", agree? The next guy, let's name him Joe, confidently believes in Nazi ideology or the bollock from Hitler and had thought about it thoroughly. Is he selfless?...

I think the problem is that you implicitly assumed an ideology (e.g., fascism, communism) not respecting "individual rights" would eliminate the "self" in its part. (I know sociology texts made a lot subtle statements that groupist equate no self and might have subtly influenced in how we communicate)

Now, read your own statement again "It's brutally selfish towards outsiders, and brutally selfless within." and apply it to you. Your cells are brutally selfless within (the requirement of developing you, the yourself), but it might or might not be selfless towards the outside, agree?
