Add a license

This repo is missing a license!

I'm considering the MIT license, but I'm not sure.

Which things are you unsure about? GitHub has great resources on finding the right license.

I know of choosealicense.com and opensource.guide.

I reread parts from opensource.guide and found out what I'm sure about:
I would love to make the project as public as possible (copy-left / public-domain / ...), but I want to protect the project and any people involved. A simple example: I don't want a homophobic / queer-negative group to use anything in this repo, since that would defeat the purpose of this project.

A code-of-conduct could help. But as it's not a legally binding document, the license has to cover the above. (Is that true?)
