liberal, conservative, whatever..
object to unjustified wars on a basis of their own lack of merit, or their 'injustice'.... not due to party affiliation.
I call myself neither strictly conservative or liberal. I let others apply whatever label they want. I did not complain about war against al Qaeda in Afghanistan. I did complain (and loudly) against the Iraq invasion, and I continue to do so.
Utopia is pure fantasy.... never existed and never will. But why not at least take tangible steps in that direction? Unnecessary war and antagonism are simply that. Unnecessary. We still have our free will.
