Woos aren't aware of it. They don't know why we accept or reject various ideas. All they know is that we're often on the opposite side of the debate. They'll make up stories about how we weren't hugged enough as kids, how we were "hurt" by some member of their group, indoctrinated into a nonexistent philosophy, just want to be nasty, or whatever Hollywood narrative they like. They do this because they don't know how we think.
That's why so many woo trolls are unable to speak with us as people. They're ignorant of what it means to be a critical thinker, and often willfully so when they refuse to listen to our points. They can't attack our actual beliefs because they're unwilling to learn them. That's why they resort to straw men, ad hominem fallacies, repetitive propaganda, and defense mechanisms. Their unwillingness to listen to us serves to compound the problem.
By the same token, many, many trolls have an unwillingness to commit to or even speak of any claims. I've had countless arguments where my fellow skeptics and I repeat various demands for clarification on the beliefs in question, only to get stalling tactics and intentional vagueness, followed by another volley of ineffective attacks.
The bottom line: Most woos who engage in trolling are poor communicators and don't care if they are. They don't care what we actually believe. They don't care about defending their beliefs. They only want to beat up figments of their imagination.
At least we can try to have fun seeing if they'll actually react to something they don't expect. Half the time, I search for weird angles of attack in hopes of inspiring a Work Time Fun response.
