So I watched this. Your interpretation of it is thin-skinned at best, laughable at worst. It doesn't do anything like drag the "entire" gamer community into anything, nor does it "vilify" the app. It describes one place from which part of a fringe group emerged, and how that group was able to connect and build its voice.
Why's my interpretation thin-skinned & laughable?
I got that youtube vid linked to me via an American Discord server the other night and nearly everyone on the server was taking the piss out of it.
Just going off the Vid title 'How
gamers are facilitating the rise of the Alt-Right' can you not see why? considering the whole way the vid is put together from the spooky music, the klan imagery and even the gaming clips used. It's purely pandering to the left's paranoia about some supposed 'bogeyman' within gaming and why Hilary lost.
A lot of gamers already have a lack of trust of mainstream media because of what previously happened with gamergate. 99% of gamers involved with it was due to a genuine concern regarding ethics within game journalism, but funnily the gaming media (and the mainstream media) only portrayed one side and that was purely about the abuse some feminists got within the gaming industry by a few absolute dickheads.
With the rise of bloggers, streamers & youtubers etc mainstream media is losing control of any narrative and hasn't got a clue what to do about it, so are lashing out in all directions. That youtube vid is seen as just a continued attack against a sub-culture they don't understand (or control), and it's pissing people off within gaming and making it so that they won't likely trust anything shown on NBC in the future.
What's worse is that people who normally couldn't give a shit about politics, and would normally sit on the fench and not get involved, are quite happy to side with Trump just to be able to shove 2 fingers at the likes of CNN & NBC.
18k downvotes against 200 upvotes on a youtube vid watched 58k times really takes some doing.
So until Hilary's side (supporters & media) try to understand & accept what's going on, they're making things worse and not doing themselves any favours. They would be better just ignoring it, or get better at memes :)
And your view that that a fringe group 'emerged' from discord; did these type of people not exist before discord ? do they not use other social media?
