As I already said, the rest are made up of homosexuals and men called to marry who shoehorn themselves into a celibate lifestyle and are miserable.
You are correct. I agree 100%.
You are accusing him of overstating his case (which is probably a fair accusation), but then you do the same. How can you know what these priests were called to? Discerning a vocation isn't something where most people can readily look at the man and say this one is called to this or that. Unless you have a special gift for reading souls, I'm left to assume you are merely reading the sad state of affairs today and making an assumption.
However, that assumption is unwarranted. A man may have sinned by having an affair while in the priesthood -- as so many of our now married priests did. These sins do not mean that he didn't have a vocation, just that he didn't life up to it. If I were to have an affair and cheat on my wife, would that mean I hadn't been called to the married life? Of course not. My sins do not change what my vocation was.
Like you I see the current sad state of affairs and make guesses about things. I see the number of late vocations, men who had a career they are now leaving to enter the seminary, and I think that for a time so many men were called, but ignored it, or missed the signs. Now, they are starting to hear the call, and returning. But I can't know that for sure, its just a guess.
We cannot know how many men were called to the celibate priesthood. Only God can know that.
