It's the usual "straw dolly" ...set up a false assumption and then knock it down..How clever are you!
There are/is at least one/or more alternatives.
1) The Heimlich is not without consequence...and can cause damage.
Inappropriate intervention..particularly by amateurs can/could/perhaps should leave you open to assault charges
2) Not all "choking" is appropriately treated by the HM..eg. serious internal regurgitation and vomiting. However
3) I would say the BEST treatment is to:
Perform the appropriate action, (if you know how/are qualified/can actually accurately diagnose the condition)
and ALSO pray.
Most good doctors get this!
Some would say..'well prayer can't hurt'
Others, myself included have experience which suggests that when I put my arrogance aside; Prayer does considerably more than just 'not hurt'
As for the esteemed Professor Krauss, one would expect considerably more intellectual integrity than the establishment of such straw dollies ( I do recognise that he may not have been specifically responsible for this meme...but I suspect he did say the words!)
a classic straw dolly
just bash it and it will fall apart!
