Be honest, do you really actually fear cringing when you re-read your stuff months or years from now? Sounds to me like an invented reason to mask a much more plausible fear: Looking foolish in front of others by saying foolish things. Well in case you do make a fool of yourself you always have the option of admitting “back then I was foolish in saying that and I have changed my mind because of X”. In this communuty being able to do that is usually accompanied with a slight status gain rather than severe status punishment and ridicule, so no need to worry about that.
