If time is symmetrical then retro-causality exists, so how can realism hold? How can the outcome of a coin flip today have a definite value independent of the observer if next year or next millennium someone can cause a change in today's coin flip? If realism holds under those circumstances then the word "realism" has no meaning. And by the way, if time is symmetrical then there is no point in ever actually performing an experiment because you would remember the future as clearly as you remember the past, so you would already remember the outcome of the experiment just as clearly as you remember setting up the experimental apparatus.
