How many cases do you know of personally where ACS put each member in a caring and frum home? As far as my experiences, ACS puts children into homes and people put on “shows” when the ACS worker comes to “check on that foster child”.
ACS workers are regular people who work because they have to! Many times the children are put into homes where they are abused too!
How would you like it if someone says that the way you discipline your children is abusive? How would you feel if someone threatened to take your children away?
You might say you are not abusing your children but guess what? ACS will act on any call, and they do not make a difference between regular discipline and actual abuse because they do not have enough manpower to really investigate… and because they do not have enough workers that really care!
Obviously if you decide to ask a rav or not is your decision, we are required to let a rav decide if we should call only because he could use siyata dishmaya to determine if calling could have WORSE EFFECTS THAN NOT CALLING! as it says “asay lecha rav”!
