I don't think you're insinuating that I'm a Randian; but just for the record, I am not.
I think my issue is your use of the term "real world", as if all individuals live the same reality. It's why I frequently must ask posters define terms such as "the greater good." It's often an attempt to encompass others' beliefs under your worldview's umbrella.
Life is compromise
I agree and that's why I find it extremely improbable for a pure theory to arise in practice. However, stranger things have happened and disastrous upheaval certainly can too.
They cannot be reasoned with
I find no reason within those who advocate and/or support our current political climate.
I have no patience with fanatics or true believers of any stripe.
How does one lack beliefs?
