You’re free to state your opinion on the internet, however when someone is rationally trying to express their thoughts and feelings and you speak in terms less than friendly (without even knowing the person) than you’re just making yourself look like an idiot.

I don’t particularly like to use that picture above since people tend to be very sensitive about such a thing, but unfortunately, such is the case.  What’s the point of arguing with someone who won’t listen or won’t even bother to look at your side of the issue?  But I guess that’s what blogs are for.  So that even people who don’t have the maturity to behave like an adult in a civilized discussion can also make themselves known.  With or without a point, it doesn’t matter, but if you’re going to act like a jerk in response to a perfectly calm reaction, then don’t bother replying at all.
