Yes. Like when you cross the road there is the possibility of harm (tripping on the tar, getting hit by a car, falling down a manhole etc) but crossing the road isn't a harmful action.
"If all mankind minus one, were of one opinion, and only one person were of the contrary opinion, mankind would be no more justified in silencing that one person, than he, if he had the power, would be justified in silencing mankind."
~John Stuart Mill~
