What is the reprobate mind?

I was just summarily banned from another forum online, this time for "hate speech" for the simple "crime" of "existing while Catholic" (more specifically just correcting some blasphemy against Catholics and my Mentor Venerable Fulton Sheen.  Just before I got banned I said the most enjoyable thing, that perfectly encapsulates what a "reprobate" is.

On Meekness, nominalism, action movies, effeminacy, and how the worst problem in the world is actually “toxic masculinity” after all!

Like Chesterton said, “what is wrong with the world is that no one asks what is right.”  Like Chesterton also said, “reformers are usually right about what is wrong but always wrong about what is right.”

So what is right?  Meekness!  Lack of meekness is what is wrong with the world.  Meekness is to do what you ought to.  Be loud when you need to be loud, but no more.  Be silent when you need to be silent, but no more.  Be angry when you need to and fight only enough to neutralize the threat, then no more.

What is wrong?  That's going to take longer to explain!
