Stop. The jargon schtick is totally about shutting things down. Or blocking specific views or ideas from being contributed or considered.
And no one actually used the "elfgame" crack in this thread. What's being said is the idea that when it comes to D&D, one person's idea of what's "realistic" is no greater than another's, even when they differ.
For example, the idea that a person can't intuit how well defended someone is from attack by observing them is "unrealistic" is just as personal as "no way can this group of human warriors actually stand toe to toe with this dragon, let alone slay it" and similar sentiments.
We all pick and choose what "makes sense" or "seems realistic" and we absolutely turn a blind eye to plenty of things that are totally unrealistic. So "it's more realistic" isn't really an argument anyone should be making to support their preferences about D&D.
No one is saying this to hurt your feelings anymore than you intend to hurt anyone's feelings when you state your opinion on the matter.
