Is anyone else worried about what might happen if we choose to abandon freedom of movement during Brexit negotiations?

One area of concern is we would require visas to travel to the continent and may be required to declare convictions! This is unbelievable! Our right to travel, move freely and live in Europe is under threat. This is an extremely important issue that affects all of us and I'm surprised it hasn't been raised much on this forum. One would think that as time goes by, a country becomes more civilized- in a civilized country the citizens have rights- such as what we have currently with EU freedom of movement. However, that's not the case with the UK as it seems we're gonna be hit hard by the impact of Brexit.
