I wish that were true, but it's not. People will flame mildly stated opinions as much as they will blunt statements. I think your point is more valid in less technical contexts, where being blunt can cause personal offense. But around here, the offense is a given -- it's driven by the technical content, not the tone. You can be as deferential an Apple fan as you like and the Android posse will still attack.

On balance, I don't even think this is a bad thing. Keep it short.
