It is not a railing accusation against any person. I call "Hollywood" "Hellywood," but it is not a railing accusation to which evil is transferred, meaning "exchanging evil for evil" would have to be done towards an individual, not against inanimate objects or institutions.
I've used the phrase "James 'Snow' White" because he's notorious for snowing people with his false doctrines. However, calling him "Andersatan" implies that Anderson is Satan, which would just be a railing accusation without doctrinal and evidence support.
Yet, on the other hand, some names fit, but only when there is a description given with it. Jesus called religious leadership vipers and hypocrites, but when He did so, He explained why. That's really the difference in the "name-calling" aspect; it's whether or not explanation is given with it, and though I won't claim to have a 100% great track record on this, you'll notice that I do take the time to explain why I call something a name like that when I do it.
