I guess I have to place myself in the 'disagree' category with PE (sorry PE - you know I adore you!).
As hinted at by OS in his first post to this topic - in the US, we honor those we respect on their birthdays - Washington, Lincoln, MLK (all federally) - they are each honored on their respective
birthdays.
Wertz, one of the most respected and honored

members to date, deserves to have his birthday remembered among us,
his community. I don't want to stop remembering Wertz,
especially on his birthday. I know how much I personally look forward to getting birthday greetings from all of you on my day; Wertz deserves the same, if not more, IMHO. Plus, frankly, it's not like any of us are obligated to post something regarding each subsequent birthday. Merely remembering, in our minds, may be enough. I'd still like to have the yearly reminder.
Acknowledging Wertz's birthday provides

with a useful reminder of the mature, civil debates we strive for here. What's the harm of honoring one of our most regarded members, despite his passing, on the day he first graced our earth? Erasing the calendar reminder of his birthday does a bigger disservice than it does good, wouldn't you say?
