Could have gone for "We had vehement disagreements but I'm sorry to hear he died" but no, you had to just come in and shit on him. Spare us the "I don't do pieties" line; there are ways to say we didn't agree and I really hated some of the things he said without being bitter and insulting. It says more about you than him and none of it good.

Also, "...pompous..." really brings pots and kettles to mind.

Pretty disgraceful post.
