There’s nothing in that definition that hints at it being a slur of any kind.
It does however give several examples that suggest the word is generally used in the context of a topic a majority thinks is bad. PT apologists makes sense, TLJ doesn’t.
Depends how you define “majority” in this case:

The overwhelming majority of critics think TLJ is good. A slight majority of fans think it’s bad.
I’d also argue the “examples from the internet” in that definition are also examples of how the word has come to be misused over time. I’d prefer examples from classical literature before everyone got online and became generally less thoughtful in their reasoning and their writing, and you could go to “print” without an editor helping you catch mistakes.
