I think a lot of them would have to. Oddly enough, I think a lot of them would like it. I know a priest in his 40's (just after they stopped having to learn Latin) who has bought himself a "Teach Yourself Latin" book and sits up at night working on it. He says the NO and he's not affiliated with a Latin Mass movement; he just thinks it's right, but he doesn't have the background to be able to do it.
Bless his heart, and thank God for our holy shepherds, who still continue to seek.
