Don't smirk -
laugh
mock
be outraged at the ethical cowardice you see around you.
take cheap shots if you have to and don't back down.
Point out the hypocracy, the personal failure of anyone who would march against the great bugaboo america but not over a war in the congo that kills millions.
Convince them of their moral vanity - their penis-envy. Their self-serving hatred of anyone who has ever succeeded. Their distaste for personal responsibility.
Laugh heartily and live by your beliefs.
If they keep drinking the herd mentality kool-aid, then that's up to them. The truly vulgar despots of the world will be able to compost them.
