You seem to be arguing with yourself here. At first you suggest that people should find their own way of doing things.
And then you seem to suggest that people should use BBF because you and your mates do.
Read what I wrote - you categorically said "It's just as easy to do all that with the focus operation set to the shutter button" and I pointed out that it's not true for everyone, by giving a counter example. I suggest only that you refrain from putting words in other peoples' mouths.
