Over on English Language & Usage, the policy is that questions about offensive language are of course on topic, but that such language should be excised from question titles, on the basis that titles appear right across the Stack Exchange network, including on many work-related sites. They even censored the fairly innocuous words tits and boobs out of a question title.
Given that, should something be done about the Lloyd George question, the title of which contains a far more offensive word?
We should remove any unnecessary offensive language, but I don't think we should make our titles worse to remove such language. Mangling the words like n***gers or so doesn't make it less offensive in my opinion, and I would oppose any such edits. If that word belongs in the title, it should be there. If it doesn't, it should be removed entirely.
The titles are the most important part to allow users on the site and using search engines to find the question they are looking for. Changing the titles this way would make it harder to find the question.
This specific title is also clearly recognizable as a quote, which removes most of the offensive character in my opinion.
If the language is an essential part of the claim, and part of what would make a title useful, then it should not be treated differently than any other word. If it is superfluous, sure, leave it for the question body.
Especially grating words, such as trigger words (e.g. "rape"), automatically exclude questions from the hot network list.
The rest is actually tolerated (of course, if it's not brutally gratuitous!)
