Also, I think that it would be wise for people to just state their opinion and let it speak for itself, instead of always needing to have the last word.
Certain posters always want to have the last word.... it's pretty obvious, if you look at the posting histories.
You'll never change the other person's mind, so it's pointless to try. Know that others will read what you say. Many people will read it and never post.
Try giving a little bit. Let the other person feel good, even if you disagree.
