Go with friends who pretend to be strangers in the crowd.
The friends go up to you and ask about your cool Q shirt. You tell them some stuff and they react really interested.
Bystanders watching.
The "still-uninformed" are people who copy what they see. Maybe they will be interested if they see other people are.
Better have some of your planted friends come from work in a suit, or act gay, to appeal to the libtards.
