I'm stuck wondering now why there's such a weird reaction to this. To my knowledge, I didn't say or imply anything offensive or even worth disagreeing strongly about (it was more a conversation starter, since there were no comments yet), so am confused. Is there some misinterpretation that I'm not seeing that's leading to this?
