I am really not sure, but edge a bit towards 'no' so that is the way I voted.
If you mean prone to 'taking the bait' of a troll, I would have to say no.
In my mind, the more passionate someone is about a subject, the more susceptible to trolling they are.
As for being 'trollish' I would say those that trolls fall into a few categories:
1) Those that are playground bullies and enjoy causing strife.
2) Those that have little command of logic and/or difficulty putting their idea on paper/pixels and allow themselves to get frustrated.
3) Those that have no true basis for their stance, yet want to convince others they are absolutely correct.
4) Those that allow themselves to get frustrated with a troll and end up responding in kind
I think trolls are more likely to
USE religion, politics, gun laws, abortion and the environment as they are issues many people have strong feelings about. So using one of those topics gives them the best shot at getting a fight started.
