i don't see anything wrong with wanting pictures of folks who've done great things in church history being placed at bus stops.
it would sure beat the condom ads, homosexual propaganda, and militant athiest darwinist advertisements usually found in these places.
Protestantism seems to have led us to a situation where showing church heros is frowned upon but showing pagan figures and symbols is commonplace.
You would if it was Martin Luther or John Calvin's picture. :O)
