What we're saying is that it's usually ridiculous to say something like "X is bad because it's from video games," because it's often not from video games, and when it is from video games it's also from everything else, which makes it abundantly clear that the fact that it's from video games has nothing to do with why you dislike it, which means that we end up having to guess at why you dislike it.
Except to the speaker, it IS something from videogames. That may ultimately untrue due to a lack of exposure to the true origins of whatever, but the speaker is not trying to obfuscate or lie. It's like someone thinking Blondie did the first version of "The Tide is High."
And in many cases, such as my personal experiences or those of my friends, the origins ARE from videogames.
What WE'RE saying is don't guess, ask. Or if that's too much, ignore. Don't ask us to change terminology because you don't like it.
