It is 100% Ossur to throw bleach on anybody, just as it is 100% Ossur to throw any stone at any car on Shabbos or any other time.
Plenty people became religious thru attending a Seder nite invitation, or Shabbos meal, or Chanukah lighting invitation or being invited into someone’s Sukkah, but no-one ever became frum from having bleach nor stones cast at them, nor from Tzeni’us policing.
People have even become motivated from having flown to Israel with El Al, and praying at the Kossel.
