I have actually had this discussion several times with my wife, mother, parent in-laws etc. I think it's quite important and exemplary of many of the issues of the Jehovah's Witnesses; it is a matter of straining the gnat and swallowing the camel. When it comes to meat, in order to observe the no-blood policies, animals would have to be slaughtered by incision on the neck and then bled. This, of course does not get rid of all the blood, but it is the first step to getting rid of most of it. Though, in theory JW's would agree that this is the correct manner of slaughtering because it is prescribed in the bible, most will not do anything to ensure that their food was slaughtered in such a way- buying kosher or halal, for example. This, to Jews and some very strict Christians would be a direct violation of eating "kosher" or "abstaining from blood".
On the other hand JW's die from not accepting blood transfusions. This how it is an example of straining the gnat. - Blood transfusions are NOT a form of diversion, they are medical procedures that are usually done in life or death situations; and of course the Jewish law is abrogated under life or death situations. On the other hand, JW's violate abstaining from blood every time they eat meat, according to the Jewish laws- and it is very much the case that JW follow the Mosaic law or the Hebrew precepts as precedents for their "abstain from blood doctrine". The point is they can't be bothered to make sure their meat has been bled, but will die in order to not receive blood in a medical procedure.
