You referred to his post as a temper tantrum (subtext: he's being childish), refer to him as someone who just wants more "toys" (subtext: also childish), and just had to point out that his points about PHP were obvious (subtext: nothing interesting to say). Then you suggested that he might be a drama queen (subtext: too numerous to list here). That may not reflect your feelings, but that is what you communicated, whether you meant to or not. It's the nature of electronic communication- it's very easy to misinterpret. Maybe you talk like this in real life and being somewhat hyperbolic in your choice of words is a humorous verbal quirk, but none of that comes across electronically.
