Ubuntu – apt-get autoremove removes everything

I'm running 13.10. I removed emacs, and then ran sudo apt-get autoremove, but it decided that it needed to remove all of these other things (a lot of which I probably need). Here is the full list:

The following packages were automatically installed and are no longer required:

Use 'apt-get autoremove' to remove them.

I tried installing and removing emacs again, but still it insists I remove all of these. libreoffice and python-twisted used to be on here until I set them to manual install. Why does Ubuntu want to remove all of these?
