I would love to see the smoke detector crowd deal with real issues that are harming people, like; domestic abuse, child abuse, molestation’s, etc. That, they sweep under the rug and the fact that molestation’s do drive people off the derech doesn’t seem to matter to them, just the lack of smoke detector is the cause of all the world’s ills.
Its much easier to blame society ills on smoke detectors and easier to give mussar on them than do the same for molestation, abuse, Finances, Agunahs etc
In life you cant fight every battle, you have to pick and choose them . You have to pick which battles you think you can win and which you might lose (but still win a moral victory) and those which you fight that you will lose more than you gain.
