If I was that woman I would have called 911 and had you arrested for harassing me. You tried to and maybe you succeeded in intimidating her. You tried to take away her right to choose what to teach her child.
I say this in the nicest way. Your actions were hypocritical.
Who are you to decide her choice of taking her child to something she believes in is abuse.
I have taken my children to several peaceful demonstrations for my pro-life group and I consider myself a very good parent.
