I have extensive experience with the NHS (unfortunately) and have pretty much always been very well looked after. The only exception was probably maternity post-delivery, but that's not anything to do with the fact that it was the NHS. But that's irrelevant. You can prove pretty much anything with personal anecdotes - what matters is the big picture. If you're against the NHS, you should probably put some thought into answering the question of "How do we stop poor people dying from preventable conditions?" (assuming that this is a desired end goal). Also, Bupa aren't going to take you to the hospital at 3am when you have severe kidney stones, or unconscious after having been hit by a drunk driver.
