However, lots of Catholics don't believe the Protestants are real Christians and visa versa

Correction. Catholics aren't that exclusive anymore. Mainstream Protestants aren't either. It's largely the American brand of evangelicals who think to be the only real christians. And the ones falling to their proselityzing all over the world.

Well true - Pope Francis is more welcoming.  He's a lot better than Pope Benedict Arnold, who flatly said that only catholics were real christians and that only catholics would go to heaven.
