Very few people use the word pride to mean self-respect;
I looked up a few dictionary definitions and they all have this meaning listed at or near the top. Merriam-Webster's "a reasonable or justifiable self-respect" seems representative. Pride as a feeling aimed at oneself is a feeling of self-worth.
I'm not sure where you are getting your assertion of "very few people" but this is an ordinary way to use the term.
that's a meaning the word has taken on as a result of being used by movements like these.
Nah. That gets the etymology of the term wrong. You've reversed it.
And even if the word choice was as deliberate as you're suggesting here by every member of each of these movements, the possible confusion you're referring to is the reason it's a poor word choice for a movement.
Oh, I think you'll find any term that says disfavored groups have worth is going to run into some semantic confusions by people who don't like that.
Pride over your accomplishments doesn't necessarily connote cockiness, by the way.
The term pride, as applied to accomplishments, does connote cockiness, though. Excessive pridefulness is closely associated with the word pride in that context. Pride comes before the fall Schmo. In the aforementioned Merriam-Webster, that specific definition adds the term "conceit" right to it. It doesn't have to mean that, but that's why I referred to connotation.
