You are probably right. But as a LOL hater I find your reaction totally overdosed. I mean, you state that you lough oud loud just because somebody wrote something you dont agree with. I try to imagine how you start a frantic loughing sitting on your chair in front of your PC, like a crazy guy.

I personally dont use LOL at all. First of all the reader will get the impression you are a kid and later it leads to misinterpretation just because a healthy personality would not start to laugh oud loud in real life only because some other person has another meaning. This is not like adult people behave, but I remember that we acted that way as school kids.

This is not a personal attack, I just want to help to show how this can lead to to a wrong interpretation of what you want to say.
