When I had no understanding of what was going on, I didn't like it either. Now that I use it frequently, I understand it better, so I don't hate it anymore.

I like running `git rebase <main-branch>`, where <main-branch> is typically master, in my-new-thing branch because it lets me deal with any conflicts from upstream one by one.

I also like running `git rebase -i` in my-new-thing when I have a bunch of commits with redundant messages that I want squashed into a single commit before I push the changes. Basically anything that requires messing around with a range of commits is a good use case for `git rebase -i`.

Why do you hate it so much? There's really not much going on that you should have to hate. To me it's like a bunch of small, compartmentalized merges.
