the overall tone of your dialogue with them is not at all mocking.
its reasonable. which is what they want.
just accepting and entertaining discussion with pedos as if their sexual preference is ok is called "validation".
frankly it doesn't at all have the tone of just stirring up outrage for shits and giggles.
for example, his first defense was an appeal to normalcy. "I've talked about this before, what are you so mad about"
trolls will make tenuous but extreme arguments, not try and normalize.
they are seeking validation, not outrage.
