"That's all-right, I'm open to having my thinking updated"
I do not disagree with you, I also think short term suffering, (if we are sure, there are no long term consequences) are to prefer if it shows it has long term benefits.
No need to be all defensive about it
Bad habits can of course cause negative consequences, only a fool would disagree.
Free individual, yes, the question is not wether or not it would be wrong to upset the baby and let it cry, if there is enough proof and evidence that the baby will indeed not suffer any long term consequences, I would be perfectly fine with short term suffering, the problem is, we simply don't know what the long term consequences are. That is the real question here, and what is important.
