Not to start a debate (laughs the ENTJ), but I feel it's a little hypocritical for someone who is far from sensing to make an argument based on past actions (say 20M dead; thank you Stalin), especially when we NT's love principles so dearly.
And where does principle stem, if not from the "non-aggression" principle?
This is the moral switch; your heart may be in the right place, but you (and everyone else, for that matter) still don't have any divine authority over mine.
As a matter of course, both of our goals should reach the same (nearly) end, but with one major difference: If Marx had his way, government would be the ONLY factor, not disappear. In fact, Marx's largest error (and the one which makes his theory unattainable as he wished it) was to blame the business-owners when he should have blamed the government.
As always, I'm not being personal; I'm just an ENTJ.
