I didn't believe you so I looked this all up and indeed everything you said is correct. My GR professor was famously one of the worst academics at the department and he never taught us any of that. His specialty was GR too.
Anyway, your response was needlessly hyperbolic. The only two misconceptions you are correcting here is that tidal forces can be quite weak at the event horizon and the universe does not come to an before passing through it.

This is disappointing, but unfortunately I don't find it surprising. I have learned GR by self study over many years, starting with borrowing my office mate's copy of Misner, Thorne & Wheeler when I was in graduate school; I never actually took a course in it. But the reports I had from people who did were that the professors did not do a good job of explaining things. Unfortunately being good at research and being good at teaching are two very different things and not many people have both.

I did correct those two misconceptions, but those weren't the only ones in your post.
