So let's do it now. Let's have a serious discussion. Would you agree or disagree that it's pointless to let things on a computer screen bother you enough to react when it's out of your life completely as soon as you stand up and walk away from the machine?
I really hope you weren't offended and I mean that in all sincerity. It doesn't seem like you were offended so I'm happy about that...it may surprise you to know that in all actuality I detest bitchfests. I'm just a sucker for proving a point.
To answer your question, that would depend on the manner in which one reacts to reading something that bothers him/her. Would I spew soda all over my keyboard and then light my monitor on fire and punch a hole in the wall then make personal threats to the person? Of course not...to me, THAT is the definition of taking the intarweb too seriously.
However, responding in kind to something posted on a forum, even with sharp words occasionally (hopefully not insulting or berating), would absolutely be appropriate. That's what it's there for; we can't all be made out of sunshine and popcorn farts.
I get this feeling from you (and please correct me if I'm wrong) that you feel by not blowing off or ignoring an argument, you automatically are vulnerable to ridicule. It seems like maybe you feel that responding to someone seriously on a message board makes you look stupid, almost like your friends are watching you type and you want to save face.
You see, when I read that big long response you posted, your point of view was made much more clear than posting something short and sarcastic. The people here who try to be funny with sarcasm really aren't; they're just being assholes. By now you know I'm very opinionated and have points of view that many would consider me an asshole, and that's perfectly fine because that's who I am. But I'm not trying to hide behind passive aggressive sarcasm like so many others. If yer gonna be an asshole, just be up front about it. (This isn't about you, just in general)
I do think you should just be honest with yourself and stop worrying about what other people think about you, even though you may tell yourself you don't care. There's nothing wrong with failing to live up to every single one of your expectations you've set for yourself; we're only human.
Sure, maybe you, neal, and Captain Beard will continue to gang up on me and ridicule me for responding seriously to a topic, but that's fine. It's fun sometimes. If they died today, I really wouldn't care (well, I would feel bad for their loved ones)...and that's the asshole part of me. That's truly not caring about anyone...their opinions, their lives, etc., not saying "I don't give a shit" and then bottling it all up inside. But I'm honest about it and I don't need to hide behind sarcasm or pretend I don't care to prove my point.
I personally prefer discussions in this manner, over the internet. It allows for a more free-flowing of speech, less barriers, less awkwardness. It allows me to keep a distance between my real life and my life online. It sounds kinda mean and I don't mean it to be rude at all, it's just how I am.
