The blocking feature is there for a reason. I wouldn't feel too bad using it. After all, it took mk some effort to code it; would be a pity to see it go to waste.
HA. What a great answer. It took mk time to code, so use the damn thing! I agree though, this isn't Facebook so you shouldn't feel "bad" about taking that action. That said, there is a real question as to whether or not you will be missing out on the ability to have a meaningful exchange with your "opposition." That sort of thing is quite valuable. I think I know who they are referring to, or maybe it's me, but either way I'm pretty sure there is room for some meaningful dialog. What I will say is that if it's "one" person, that is what those functions are built for. Tailor your experience.
Your second paragraph is the heart of the issue. He's around so often that I feel I may miss some good debate. And don't worry, tng, you're absolutely one of my favorite users. You always contribute something interesting, to the point where I don't even know if you've posted things I disagree with because I always find what you sayiinteresting or provocative, so the actual opinion is secondary to the exchange of ideas.
Only you can make this call, I suppose. I've not really ignored or muted anyone because nobody here really offends me. Most people that have differing opinions seem to be able to back them up with some sort of reasoning, even if their reasoning also seems counterintuitive to me. I guess for me, the most important thing is that people have thought through their opinions and I've yet to find a really opinionated, prolific hubskier that doesn't fit that description. Also, thank you for the compliments. Now I feel compelled to offend you though :)
