Always be kind, and take their logical argument to the nth degree. Example:
A. You know welfare helps blah blah blah....
B. Perhaps we should all get welfare then!
A. Global warming happens because of energy blah blah blah....
B. Why not just get rid of energy altogether and save the planet?
A. Obamacare is great because blah blah blah....
B. Yes, it’s so sad to people in our own government quit because they fear it so much.
I only do this in my head. Liberals are trouble makers, especially when they wield power.
I’ve had a lot of success when inefficiencies occur between my company and various government agencies that we deal with. “Why don’t we put them in charge of our health care too”, usually gets an uncomfortable chuckle which I can see strikes a nerve at the same time....
