Point out what freedoms have been lost, and that the impetus seems to just be beginning. Ask him/her what benefits were received from the Bush tax cuts. Ask how many soldiers have died, and if s/he doesn't know, have the figures. Ask why his/her grandchildren will have to pay for an unjustified war. Make a list of the proven Bush lies.

Make a written list before you go, so you don't get sidetracked in conversation.

(pant, pant!)
