Not sure you should be equating kids to to grown men, or ignore who started this mess.
But besides that, don’t forget:
-Lying
-Lashon hara
-Rechilus
-Potential rodfim
-Making a mockery of the Torah
This list can go on and on.
since I don’t know what they said , I don’t know if they were or were not oiver on the issurim you mentioned. It wasnt a question of equating, nor does it matter who "started up ". I just don’t understand how anyone can condone what happened at the protests . I would have pitied my younger self had I been caught by my parents at such a protest.
I specifically said 2 wrongs don’t make a right.
And just out of curiosity how do you get to rodfim?
