There are two things that infuriate me about MN, and I'm sure it applies to other internet forums as well:
many people (you know who you are...) make sweeping judgements without bothering to read or understand the facts
the word "choice" is misused time and time again
I have been on the receiving end of both of these and I try not to do the same to others. This is an anonymous internet forum so it's to be expected, but I do think it often brings out the worst in people .
[But there are lots of lovely, helpful MNetters out there too ]
