I can only suggest that the thread in question was starting to get a little.... heated.
Not saying strong opinions on either side of a fence aren't worthy (they make for the best debates) but the last few comments I think started to take it to a new level. The last accusation was a bit on the libelous side.
I think your list was a good one - I think it should be fleshed out as a resource in the resource section. Perhaps as a standalone list (a composite including the [positive] input from others) would make an excellent reference.
