I would like to see one of the fathers actually lose it on live camera in the following manner:
“It’s all your g88 d888 m88888 f888888 fault, you Muslim loving s88 o8 a b8888! where is your protection, now? Huh?”
and immediately spit on his shoes!
All they need to do is sit down, take off their shoes, and turn the soles of the shoes towards him as he speaks.
He will know what they mean.
Silent, yet very insulting without threatening.
