This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

What about time travel? They had a pocket time travel device and they couldn't strangle baby Voldemort? Or was there some Avengers endgame multi dimension thing preventing that?

She realized she had made a mistake introducing time travel that's why she destroyed all the time turners in Order.

IIRC Time Turners can't change the past. Whatever actions you do while in the past have already happened the first time around, you just didn't know it because you didn't travel to the past yet.

Correct.

Within that framework, HP timetravel is self-consistent and, say, Back to the Future and others of that type aren't.

Very well shown in Rick & Morty snake timetravel episode. The snakes do the inconsistent time-travel and Rick only does consistent.

Time turners can't change the past that you observed and even then it could've been an illusion or a trick. Dumbledore could've gone back in time to save Sirius and then cast an illusion making everyone believe he passed through the veil. The past didn't change, only people weren't aware of what was really happening.

That's pretty much the plot of the play Harry Potter and the Cursed Child. It's about the original protagonists' kids and time travel (and it's written by Rowling, so it's canon).

Not to spoil anything I think anyone can guess that time travel part doesn't exactly work out as expected.
