The key word there is "some." At a conference I attended on advances in bloodless surgery, conducted by a dub elder hospital administrator, attended only by invited JW elders and their wives, the guy finished and then asked for a show of hands. He wanted to know, given everything that had just been explained about the Society's current position on blood and transfusions, how many in the audience would take advantage of all the options. At first it appeared the entire audience held up hands. then he asked, "Is there anyone who would not?" Two people raised their hands. The look on their faces told me they were silently condemining everyone else in the room!
Also: In some rural areas, there are no HLC guys like the elder I've been talking about in this thread. In many cities and suburbs, there are. Wherever an HLC has at least one guy who has some education and any kind of medical background and/or reads and understands the Society's current doctrines, most of the others generally bow to his authority on such matters. So, like many other JW perceptions, it depends on where you live.
