If you actually read the whole thread, most of us are pretty level headed about this. nobody is "lynching" anyone. seriously, I do think that this thread is pretty calm (at least before you came in) considering provocative title

(I personally feel it would get a stronger outburst if the title is posted in other sub forums)
most of us do agree that oly ISO performance is not on-par with nikon/canon, especially so if you are comparing with full frame sensor. We suggest things that oly have which nikon doesn't have which MAY help to compensate for the ISO performance. Example, olympus has a f1.4 stabilized system with the 30mm f1.4 prime (which nikon/canon does not have). That helps u somewhat to use a lower ISO. but if you need a high shutter speed in low light, then full frame is probably the way to go. nobody is saying any different.
all systems has its pros and cons. Olympus pros for me is probably the color rendition, stabilized f1.4 prime + ultra wides, live view (E330) and dust cleaner (really works). cons to me is dynamic range, resolution (E330), ISO performance.
I jumped to an SD14 which hardly have any "fanatical" followers in CS. Reason being I feel its dynamic range and resolution is higher. I can print better A3+ prints and see the difference in front of me. But for that, I get a non-working AF.... non-working exposure... have to shoot full manual. I will probably switch sometime in the future.
We should not be so serious about brands. Just chit chat about our personal views, some of us like nikon, some like canon, I like sigma (duh...). It is nice to talk about our personal opinions of the brands, but when people gets too emotional about it, it usually gets out of hand.
