Yes, though this is a scenario where I'd argue such a reading is a touch overzealous, and is exactly the sort of overreaction that leads idiots to think that calling Musk's Nazi salutes what they are is just pearl clutching. The song is about haters who talk mad shit behind your back, but don't dare say anything to your face. Therefore, "boy" is being used to imply the narrator doesn't consider these people to be "men", as they lack some quality (maturity, courage, whatever) necessary to qualify.

Also, the world changed a lot in the decades between the song's release and 2016. I'm not going to go digging to try and find out exactly how much of a piece of shit Anselmo has been and for how long. Fucker isn't worth my mental bandwidth, so I'm okay with operating on the assumption that, like many, many folks, he was radicalized over time by the rise of the "alt-right" and becoming wealthy. In either case, it doesn't change the fact that I've got no intention of ever financially supporting his endeavors in the future, despite enjoying some of his output in the past.
