As for those "gamers" that supposedly are out there lashing out and being total jerks to anyone and everyone , I have a theory regarding that those people are actually mostly not gamers at all but people who dress up gamers, act terribly, and then presumably do so in order to make the image of "gamers" being bad.
They tend to play only a handful of franchises, or gravitate exclusively to AAA titles and speak of gaming only in AAA major media terms, if you ask them what their favorite Sonic game was, they'll stare you blankly because Sonic isn't on the menu of things that gamers supposedly care about.
If you ask them their favorite games or best games they'll rattle off the most thoroughly conventional list imaginable, starting with the likes of Half Life and ending with the likes of the Last of Us, as if this all began and ended in the last 10-12 years.
Most of their time is spent keyboard pounding on social media and/or gaming websites, and not even really gaming at all, trying to get as many people as possible to buy into the notion that "gaming" is somehow bad under the guise of defending it and a false cloak of social justicism.
The truth is many of them still worship at the idol of Hollywood cinema or something, and are straining to incorporate a different paradigm of thought and expression that is oftentimes just beyond their fingertips, and rather than embrace it as a whole, they invent or distort images within the sphere of "gaming," re-arrange labels, and at long last launch a volley backwards over at the medium they're presumably protecting.
