Just a few thoughts to clear up some misconceptions on blogs.
First, I do value the opinions of my readers, as long as there's a degree of respect given to my blog. In all of my time on joeuser, I have only deleted one response, and that was because the response was so vitriolic it wasn't worth commenting on. I won't allow such blogs to stand on my thread.
If I feel it is important enough for me to respond, I will leave the original post. That is only fair; taking snippets out of context destroys your chance to be fairly represented in a discussion.
The thing you need to realize in regards to free speech, though, is this: Firstly, I am obligated to the owners of this site to hold true to the Terms of Service I agreed to when I signed up. I take that obligation seriously, and will use whatever tools I have at my disposal to ensure that my blogs remain within the TOS guidelines.
Secondly, I have a right to freedom of speech within those guidelines. This means that if I feel I am being harassed by an individual, or if I am just plain annoyed, I have the right to blacklist them from my site. I don't blacklist often, and have to this point restored every person that I have ever placed on blacklist, but I defer the right to use this tool as I see fit. I value comments, but if the thread's going to degenerate into a spitfight, it does you no good, and it does me no good to continue.
I try to invite and elicit well thought out discussions on my thread, and, frankly, I think I've been party to many excellent discussions on this site. But it is my blogsite, and I intend it to reflect who I am, not be filled with angry diatribes as I have seen on some sites.
