As part of my on-line activism, I comment regularly on three abortion videos on YouTube. It has really been an education of the Pro-Choice crowd. Here is one example:
I am regularly insulted in the YouTube comboxes, although I have been able to engage a couple of adversaries in respectful dialogue. My experience is that the Pro-Choice side does not take the time to make a thoughtful argument, or maybe they don't have one. So the tactic is to bully Pro-Lifer's into leaving the conversation.
Pro-Lifer's that I have seen are resilient, we are doing important work. We must stay in the conversation. We must not be silent.
