As a rule, I tend to not reply to posts that may elicit very strong emotion (in either direction) This includes, but is not limited to: Politics, Religion, War, and in this case, what can be turned into a gun control issue.
I learned this, on these boards, about 7 years ago when there was a gentleman who I just wanted to go away for his posts. I posted some comments one night in a fit of anger and was appropriately called out by Paul and had my post deleted.
I have many friends who follow the same rule, as it eliminates any chance of being misunderstood or offending anyone.
Just believe me when I tell you my heart was heavy about the recent Navy Yard shooting.
