see, i don't believe in morals, but i do believe in rights.
and, we get to make those rights up, too - we don't need a divine source or an objective truth.
but, if we're convinced of their truths, or even their idealistic projection as truths, via whatever argumentation, we should uphold them as best as we can.
yes - that will lead to conflict. this isn't just ok. it's necessary: that conflict will propel us forwards.
leftists, after all, are all about conflict. conflict drives progress...
if you want harmony, your home is on the right.
