Hello!
I see that you just put a disclaimer on The Birth of a Nation/Source. Sine I put a disclaimer on All This and Rabbit Stew/Source yesterday, this has inspired me to create a template for all disclaimers: {{content warning}}. We obviously need one.
The template takes one argument - the text saying what is objectionable about the material.
I used some of your wording and some of mine - if there's anything that you think needs to be present that isn't there now, please let me know.

EDIT: Here's a list of the pages that use the content warning template. If you are aware of any other pages that should have a warning, please add it.
