I think the issue is the way you phrased the question. The use of the word "imaginary" is dismissive. You are asking sensible questions and I agree scepticism is important for new things. But careful use of language so as not to dismiss people is also important so as not to alienate people during an important debate.
It's similar with how you replied to my comment with "please do be careful", you may mean it but it can come off as condescending.
