We’re all just stating opinions and beliefs in this area. I took issue with what you said because it suggests that everyone who is a socialist is more likely to be willing to “sacrifice individuals” (not that I am one).
There is no support possible for that statement. For as long as you insist on its credence I’ll continue to deny it.
To insist on such a characterization of any group is to set them up as viable targets for violent repression — to sacrifice those individuals for the sake of all the others who are ‘not like them’.
The ultimate goal of ‘socialism’ is Marx’s vision of communism. In it the ethos of non-civilized groups would apply to all human beings as one unified group: basically, ‘all for one and one for all’. That is the very opposite of ‘sacrificing’ individuals. (In that sense I am a communist.)
Are some socialists capable of ‘sacrificing individuals’ to achieve their goals? Yes. Are they necessarily more likely to do that than any other groups with a societal goal? As all of human experience attests, the answer to that question is, “No.”
