Steve, it is your ethical responsibility to correct any misinformation you may come across on any technical website. Once the correction is made, you are not responsible for any adverse reaction somebody may have who takes your posts personally and feels slighted. That's their problem.
Of course, it also depends on how a correction is worded. One must attack the issue - not the person discussing it. I have never noticed you attack anyone personally. So rest assured you are well within your bounds of our discussions, and are welcome to correct anyone - including myself - if you find error. I'd hate to think I steered somebody in the wrong direction without being corrected.
I've never visited a BMW website. Compared with this M-B site, do these people have attitude problems?
