You are associating the use of `amend` and `fixup` with force push. It's perfectly fine to rework your commit history locally and even force push to your own local branch. It should never be possible (except to people administrating your repo) to force-push to any public or even shared branch.

Nobody should be able to force-push to master (or any public branch) except on specific occasion. In that case, someone is authorized, performs their specific action and then get de-authorized.

This is pretty basic.
