Most people haven't been making nearly as strong causal links between media and behavior as often portrayed; it's more of a chicken-and-the-egg thing where media portrayals can reinforce and validate certain narratives and treatments.

It's clear, for example, when talking to many people that they see portrayal of minority statuses as intrusive and inherently politically motivated. It's hard to imagine that worldview existing to that extent in an environment in which a wider variety of character portrayals exist without marginalization or leaning too heavy on the tropes.

Even if "gamer" were an immediately visible status like race or sex, or one which had resulted in people being directly jailed only a few decades ago like sexual orientation, this conversation on the GG side has never really been about mainstream media portrayals of gamers; more about a particular subculture within gaming not being fellated and targeted directly for all content and all releases for the brief moments in which some article or game comes out or some developer or writer says something that they disagree with. Then they seem determined to reinforce these negative stereotypes and this garbage rhetoric, which is after all what bubbled this discussion up into the public sphere in the first place.
