The penalty of "anathema" no longer exists in canon law post 1983, so the penalty clauses of those anathemas are legally void.
Non-Catholics aren't subject to Catholic church discipline, so the penalty of "anathema" never applied in any case.
Indeed. Trent was addressing people who had been baptized in the Catholic Church. They were formal heretics. The majority of evangelicals are not. Furthermore, even Trent was concerned about the leaders of the Reformation rather than their followers, many of whom were compelled by the laws of their states to adjure their faith. Different time, different place.
