It's not the phrase that's the issue, but you knew that.
So the issue is that you're insufficiently socialized to understand this or don't care, both of which are very poor signs for someone who wants to lead a long lived organization which stewards a open global platform. IMO your behavior in this thread is very strong evidence that any org you lead is unlikely to thrive. You seem to lack the disposition and people skills.
People can argue about the boundaries of the term, but pretending nobody knows what is being referred to is not a serious argument.
The claim is that it's too broad to be useful. But as I said earlier, this is all besides the point.
The real objection is that supporters of the ideology dislike the characterization embedded in the term.
Again, besides the point.
