To feel insulted by "Yes, only a complete 'effing moron might suggest this was a deliberate attack" implied you believe this was a deliberate attack, and hence GTX is calling you a moron. So either that is what you are saying, or it isn't. If it isn't then GTX's comment doesn't apply to you, and noone is calling you a moron. Perhaps you could clearly explain what you did mean?
I broadly agree with Greg's post, though I wouldn't have been as blunt - the chance of this being a deliberate attack is close to zero, and suggesting that it was is only a relatively short leap from the braindead conspiracy loons yelling "ITS A MUSHROOM CLOUD OMG NUKEZ #PIZZAGATE #QANON".
