That's what it means to you, most users mean "something liberal/progressive I don't like".
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.
