@Monogram That's smart of you.
I'm willing to believe that 90% of everyone on this forum are not pieces of shit. I've had spats with people, even called people rude names, but despite that I still don't think it's likely at all that they're shitty people. In this say and age it is easy to lose compassion and just flame someone over the internet, just like every comments section of every CNN post on Facebook.
But the end result is that people will read how you talk to people, it might make them want to distance from you, and you'll end up being casually avoided because of your behavior on MSB during a period where you weren't at your best.
MUers may not have entirely control over how they're viewed due to the number of judgmental people (and miscommunication that happen) out there, but since most people tend to not end up paging or skyping with people who have decided to view them in a negative light, those opinions don't tend to change.
Best to be aware of that
