Just to set the record straight, workhorse, ryanthecolt, and a couple of others are not trolls. They have come here for quite a while and are always welcome. They do not post or behave in a trollish manner.
A troll post is one that isn't serious, but is only designed to annoy people, usually from someone who is not a part of the group of the forum on which he is posting (i.e., a Colts fan posting on Patsfan.com). Go back and look at workhorse's first post. I can discuss football when people discuss football, but people have been free to let me know when I step over the line, and I will certainly tell fans of other teams when they do. Someone called it a troll post, and I agree.
You are certainly welcome to welcome Colts fans here. But you don't speak for me. I tolerate ones that behave as well as I would if I visited their website. I don't go to sites of other fans because
a) I can be a caustic SOB, and
b) my internet communicating skills (or rather lack thereof) exacerbate the problem caused by a) above.
Here I'm home and like a churlish relative, I am what I am. Roll your eyes if you want, but here I'm home and you can just deal with me.
But if I did go to other fans sites and started posting crap posts, or even posted the way I do here, I would expect them to ban me and it would serve me right. If I went to another fan's site, I would have to behave as if I were a guest in their house (which I would be, virtually), and since I know that isn't likely, I stay away from them. And I appreciate it when they do the same (stay away, or behave like a guest).
