Are terms like 'mankind' and 'the brotherhood of man' outdated?

Slightly more than 50%.

Man is not kind to themselves. Thus people don’t think of women immediately. I’ve never really heard anyone referance “the brotherhood of man” before. Not sure what that is really… And yeah.. @Haleth probably around there.

I usually use the term Human

Yes, they are definitely not the PC terms to use. I read generic names like people or humans these days.
