My response in EY's place would probably be, "I'm a person who had trained himself to take ideas seriously [insert link on Taking Ideas Seriously]. I thought there might be a risk at the time, I acted quickly, and upon further thought it turned out I was wrong and yes, that's fairly embarrassing in hindsight. That's one of the pitfalls of Taking Ideas Seriously - you're more likely to embarrass yourself. But imagine the alternative, where there really is a threat, and people kept quiet because they didn't want to be embarrassed. From that perspective, I think that the way I acted on the spur of the moment was understandable".

[Edit: this is apparently not what happened and there may or may not be some sort of smear campaign or something distorting everything, although I'm confused at why it was banned here then. I'm not really sure what' actually happened now, oh well... either way, whatever actually happened, I taking a general stance of judging people mostly by accomplishments and good ideas rather than mistakes and bad ideas, except in cases of actual harm done.]
