I hope that people can start to avoid or forget many stereotypes.  Also there is the problem of names. "Protestant" is something of a negative term since it is defined as an antonym.  Another historical replacement term should be "reformed", which is not so hostile.  I see the day where the main Christian bodies still exist but people float between them without hostility are contempt.   And excellent example of such to my thinking is Vice-President Elect Mike Pence. He has sometimes called himself an "Evangelical Catholic". He never disowned his Catholic roots, even being formerly in some lay ministry as a Catholic. He says he had some needs so he went elsewhere, looking for support for more intimacy with God that he craved. I do not think the term "protestant" would appeal to him.
