Use their ideology to out-virtue them. Tell them you have a black gay homeless friend with AIDS who needs a place to smoke meth with his boyfriend. Ask if he can get a key to their apartment. Tell them he used your apartment for a while but became allergic to your cat. When they say no, accuse them of being privileged racist, homophobic fascists who oppress poor people of color. Mumble about fascist pigs every time you pass them.
