Wikipedia is not about "rights". Wikipedia is about creating an encyclopedia. All this trolling distracts from that goal. Trolls should be banned quickly and painlessly as soon as an opportunity presents itself to get rid of them.
The problem I have with that is that it's very unclear what a "troll" is. Any number of Wikipedians have been accused of being "trolls" at one point or another. Some cases are very clear-cut, but the majority aren't, and in many cases, "troll" becomes simply shorthand for "person I disagree with".
