Its always good to have those different opinions, in my... opinion. When you establish with someone (or a group of someones) that you can accept that a disagreement of your opinion, or their opinion, isn't a criticism of them, but rather of their ... idea - conversation flows a lot more freely, and is a lot more entertaining and enjoyable.
The Internet has seen so many people forget that part of human interaction.
And of course, here on HIVE, the ever present threat of pissing off someone with a downvote fetish is every present. :D
