"if humans are perennially, pathologically bad judges of what is in their own best interests, is "full self-expression" an absolutely good thing?" - this has got me scratching my noggin. I feel like there is a lot to this question. Well, ultimately there needs be be a leap in evolution away from such disastrous and dangerous behaviors we see. But I don't think that anyone should limit freedom of expression. Does a dictator have the right to full freedom os expression? This is where it gets really fuzzy for me.

The flip side of this is that given 100% freedom the action of dictators (to use an extreme example) could be addressed and halted by others who are executing their freedom and protecting the freedom of others.

Good point @wildlocusthoney! Thanks for inciting the thoughts.
