We could talk about the Biblical "watchman on the wall", but who worries about such things any more?
A person was walking through an area of homes when they saw a small fire start in one of them. There were alarm boxes in the area to alert the fire department. Yet they watched with horror as the fire quickly spread until the home was fully engulfed in flames.
Screams of the trapped inhabitants were heard, but it was too late now to save them. Eventually the fire department was called by neighbors. When they arrived, the home and its people were beyond hope.
Someone noticed a person standing near an alarm box. "Are you the one who notified the firemen?" they asked.
"No,", was the reply.
"How long have you been here?" was the next question.
"I've been here since the fire began."
"Did you warn the people in the house?"
"No, of course not!"
"Of course not? You let them all die?"
The conservative person said, "I didn't want to be called an 'alarmist' ."
