This is bollocks Jim. You refer to "us", "we", the so-called "gaming community" etc. as if you're appealing to some singular collective. What you're actually doing is shouting into a cave. There isn't this "us" really. There's just individuals that buy, play and talk about video games.
Moviebob does this kind of thing too: Lengthy seminars about what the ideals of "the gaming community" ought to be. I have to raise an eyebrow when the rhetoric gets this political. It's like there's this idea that the gaming community is political movement or something.
The only people who your soapboxing will affect are the people that talk about video games professionally, video gaming journos (and bloggers who wish they were journos), who will go on to echo this stuff. Everyone else in your viewership i.e. average joes that play video games from time to time will give you a pat on the head for letting us here a good rant but that's about it.
You should know by now that no amount of soapboxing is going to stop the occasional few, individual haters from haters and the /v/ trolls from trolling. They're going to do what they want.
Edit: On the thing about "mekkin us luk bahd" - you do realise that the "non-gaming community" [whatever the hell that is] does not give a damn about "us"?
TL;DR: Stop taking fun so seriously, ffs.
