oops, yes, that slipped. I meant: "not antagonistically".

The deniers of socialist morality assume that suppression of other 
humans, pollution etc. under the conditions of socialism is nothing 
anybody in their right mind would have an interest in anyhow, and hence 
they deny the need for any form of moral.

Apart from this (German) lecture I have not found anything that discuses 
this view in any detail.
