This is simply saying that you do not have, and do not desire to acquire, the emotional capacity to be satisfied with the social trade offs of voluntary subordination of a portion of your own personal desires to benefit the desires of others who may also want to commune with you.

So if your proof claim is simply “I don’t want to” then it’s entirely ignoring the question with the idea that it’s not your choice anyway - you’re just born that way - which is not a relativistic statement.

In fact it’s a biological determinism argument and if you would like to go down that hole I think it would yield that your claimed antisocial “preference” is extremely rare historically - to the extent where as an outlier it’s questionable if it is an evolutionary fitness trait or if it’s ultimately supporting a genetic brick wall.
