I seldom call a dead person stupid.
First of all it has no effect on the dead person, not even in the slightest way, but more importantly it does nothing to help understand what happened.

Of course there is the point that we all have our idiot moments and that I don't like the idea of upsetting relatives but I really don't worry much about that part of it.
I may be a liberal but my heart does not bleed much.
I function more like a pragmaticist and realist than as a Bambiphile.
