Yes, if records are available they should be neutrally expressed. I may or may not want to vote for someone who had been jailed for protesting, or for fraud, but I think we should know before deciding. Similarly, and perhaps predictably, I would want to know if someone making decisions about the NHS used private medicine (not that he is registered with an NHS GP, as we all are), and similarly if someone who might become an education minister sent their children to private school. I might decide that there were good reasons for doing so, but IMO the choice should be mine.
