This attitude is incredibly naive (the fact that you made an account 2 hours ago to express this opinion, means you probably agree and are just trolling). Governments change, but data is forever, what you say now or do in public may be politically neutral or acceptable at the moment, but might be worth a jail sentence in 20 years time. Your data will never disappear and you can be held accountable for something you said 15 years ago, even if your opinion has changed or if it was out of context.
For example, have you ever expressed a view about abortion, either for or against (or homosexuality, or religion, or politics? Right now any of the views you expressed may be socially and legally acceptable. It is conceivable that the legal views on this could change 10 years down the line and if you expressed a view that is out of favor with a government of the future you could potentially be in serious trouble.
