“A liberal society stands on the proposition that we should all take seriously the idea that we might be wrong. This means we must place no one, including ourselves, beyond the reach of criticism (no final say); it means that we must allow people to err, even where the error offends and upsets, as it often will.”

Accurate when considering a definition of liberal from 1776. Today's liberal mandates censorship, totalitarianism and considers everything outside their theocratical dogma an immoral error and not permitted. Today's liberal is offended and upset when confronted with individual sovereignty, inalienable rights and liberty at nature's law.

Indeed.  Because we can err, we cannot be too rigid in our demands of others and even ourselves.  Sometimes I have to sit back and review my sacred cows and make sure they are indeed sacred.  Even though I am more 'conservative' in my older age, I am also more 'liberal' — forgiveness goes a long way and sometimes is the only option other than perpetual conflict.

The Socialist, however, stands on the proposition that there is an appropriate resolution to every problem. There is someone who understands the situation and can solve the basic problems, positively. Murder and mayhem is never the answer.  A rational and reasonable responsible win-win answer can be found.
