Say what you will about American policies in the 50s, yes they were racist, yes they were sexist, and many other things. But I don't believe it is really arguable that the US was a dictatorship at that time. Less democratic than it is currently, sure. Not a dictatorship.
Trump's lawyer is currently arguing with the Supreme Court that a president could legally assassinate a political rival; and the majority of the court seems to be leaning toward agreeing. They (the GOP) seems to be aiming for instituting a Russia-like authoritarian government.
