On the other hand, it would be nice to exchange pleasant thoughts about Star Wars without EVERY thread become an argument about the O.T. vs. the P.T. I am pretty sick of that, but I shy away from banning someone just because they ... well, steer every thread to the same argument.
If that's trolling, then by all means ban him. But I think it falls a wee bit short, and is simply annoying as all hell.
