Also, it is noticed how ultrafilters play an important role in many of the impossibility theorems of social choice theory (incl Arrow’s Thm). […]

Starting from the words “now, by the hypothesis of this theorem” there is an incorrect statement, because actually there’s no restriction on \pi’ profile for elements except x and y. So as a set \phi^{xy}(\pi) can have zero intersection with \phi^{xy}(\pi) in case when some voters change their opinion completely.

What is even more worrisome is that many American’s don’t understand the work in progress.

I was just spending too much time disagreeing with the admins, trying to mod by other people’s grudges and white-knighting some TR people. I’ve never followed orders or done hypocrisy well so I bailed again. I’d tell you more but if I did that in public I’d probably start a shitstorm :). If you’re the gossipy type feel free to email me.

Now I’ll stop messing up your serious blog with crap that you’ll have to delete.

I’ve bookmarked it and can’t wait to get back to it although I know I won’t completely understand it.

I found you via your realistic comment about the Roma at secularcafe.org. I’ve been searching for other left-wing, atheist, secular types who have NOT jumped on the do-gooder-I’m-more-liberal-and-tolerant-than-thou bandwagon. I am so dismayed to see how many of my fellow atheists enjoy saying nasty things about the pope but love to defend Islamic totalitarianism.

That was pretty cool 🙂

I hope things are good – Christina.
