Dawg, it's not just internet stories...it's internet comments from white people on regular old sites like TMZ, The Huffington Post, and yahoo. Its sites like Reddit. It's social media. It's not a trend. I feel like these sentiments always existed, but now with the internet we're able to see those type of sentiments displayed on a larger and more accessible medium.
I don't really get in these type of discussions, and I consider myself a pretty tolerant, non-racist, and a accepting person who has is happy to have many friends and many fruitful relationships from all across the board, but even I have had to really re-evaluate white America in the past couple of years since Obama got elected. This country is just getting more racist by the day (don't get me wrong, it never left) and white people are just constantly throwing out this non-existent and laughable idea of a "post-racial America" (which is BS cause this term could of only been invented by people who don't have to apply to the rules of race) to justify being outwardly racist whether it's by comments or actions ("get over it already we have a (half) black president in office!"). And getting really comfortable too. Of course, it's probably just going to stay like it has been recently as just anonymous (or not so anonymous) internet comments and institutional cause it's "safe". The moment that racism manifests in in your face racism and violence like back in the day is when it'll just reach the tipping point.
The internet actually to me is making me realize how disgustingly saturated racism is in all aspects of society; media (books, music, TV) entertainment, sports, commerce, love & relationships, the underworld (drug sales and consumption), pornography, the corporate world, the government, etc. It's impossible to get away from.
Black folks are just happy to be eating at the table...it doesn't matter we eating table scraps while everyone else has a full dinner on their plate.
