It’s used as a catch-all slur to mean “evil thing I don’t agree with”, they can mean any of the competing definitions or none - I doubt if they could come up with what they actually ascribe if challenged and not in front of a computer to look up one of the definitions to find something objectionable within that.

Which is my entire point really, not really getting what yours is here though. That it has a clear definition? I mean, I don’t think it does but it doesn’t matter. It’s not clear in practical use what people refer to.
