Maybe the thread should be in Off Topic. But wherever it goes (or stays), here's my initial 2 cents.
The effects are negative.
As most of you know, I am black. While I am proud to say that, I don't make a point of telling people that on the Internet. If I forge a friendship with someone, be it a message board like this or a live chat, it will come out eventually.
Recently, someone typed something that resembles ebonics. A woman, white female in Canada, responded to that by saying "he types black."
I asked what she meant by that. Her response was that "most" black people talk that way. She compounded the error by saying it's "natural" for "them" to talk that way.
Yes, I let her have it - firmly but respectfully. She abandoned the conversation without so much as a "see ya."
But before she left, I learned that she based her opinion on 2 or 3 black "friends" she claims to have. I suspect rap videos, shows like "House of Payne" and that reality show with Flav-a-flav helped shape her opinion.
It's not just her. But I've encountered that kind of attitude when traveling to areas where there are few black people, if any at all. They don't know me, but if they know I'm black before they get a chance to know me, they're shocked when I start talking and they can understand me.
It's the attitude characterized when Bush referred to Barack Obama as "articulate."
That word is not offensive. But when black people hear it spoken by a white person, it pisses us off because MOST of are ARE articulate. It's been my experience that when white people make a point of saying that, it's because their limited contact with or knowledge of black Americans is influenced by what they see on television.
Reflecting on my Brazil trip a few years ago, most of the people I met were brown-skinned though not as dark as I am. Even so, many of them were surprised that I was 1) American and 2) I didn't speak jive.
Like so many people, they judge us by what they see on television: buffoonery, thuggishness, poor speech, bling-bling, women as objects.
Oh, and let's not forget TV news. We sometimes laugh about it, but it's downright irritating when after a disaster or mass shooting and they do "man in the streets" interviews, they seem to go out of their way to find that one black person in the crowd who's got a half-dozen missing teeth or a lot of gold in their mouths, and the person is most inarticulate.
I focused only on the racial element, but it's not the only problem with this type of entertainment. It's just the one where I see the most impact of those negative stereotypes.
