Is this the only forum you belong to? I only ask because I am on quite a few forums and this is exactly how they work. People have strong opinions and don't easily back off of them. I could just as easily accuse the other side of not seeing what I believe to very effective counter points to my position. But quite typically people are dug in. That being said, I actually did change my opinion on this trade but no one seemed to notice because they probably did not want to. I was against this trade a few days ago when this thread was first created and then I came around to not minding the trade after reading a lot of the posts saying why it would be good. So, I did in fact change my opinion based on the other side's posts.
I belong to several forums. I grew up on forums and actually prefer them to social media. For the most part I think more intelligent conversatios on there in comparison to nonsense a lot of people spew on social media.
Anyway, I think people don't notice your change of opinions because your general opinion remains the same. The over the top criticism of BB, and all these digs and points to bring out to discredit him. And criticism if warranted is fine and dandy, but not when posters see right through the reason as to why that is.
