Why is discussing race on DU considered race-baiting?

78. There are good reasons why Sanders is not appealing to African American and other voters

There are good reasons why the demographics are not working for Sanders and why many voters including some African American voters are not supporting Sanders. Demographics are important in that this explains one of the big divides between Sanders supporters and Clinton supporters. There is a vast difference in how Sanders supporters and Sanders view President Obama and how other Democrats view President Obama. I admit that I am impressed with the amount accomplished by President Obama in face of the stiff GOP opposition to every one of his proposals and I personally believe that President Obama has been a great President. It seems that this view colors who I am supporting in the primary http://www.huffingtonpost.com/entry/clinton-sanders-obama_us_56aa378de4b05e4e3703753a?utm_hp_ref=politics

But lurking behind this argument about the future is a dispute that's really about the past. It’s a debate over what Obama accomplished in office -- in particular, how significant those accomplishments really are. And it's been simmering on the left for most of the last seven years.

On one side of this divide are activists and intellectuals who are ambivalent, disappointed or flat-out frustrated with what Obama has gotten done. They acknowledge what they consider modest achievements -- like helping some of the uninsured and preventing the Great Recession from becoming another Great Depression. But they are convinced that the president could have accomplished much more if only he’d fought harder for his agenda and been less quick to compromise.

They dwell on the opportunities missed, like the lack of a public option in health care reform or the failure to break up the big banks. They want those things now -- and more. In Sanders, they are hearing a candidate who thinks the same way.

On the other side are partisans and thinkers who consider Obama's achievements substantial, even historic. They acknowledge that his victories were partial and his legislation flawed. This group recognizes that there are still millions of people struggling to find good jobs or pay their medical bills, and that the planet is still on a path to catastrophically high temperatures. But they see in the last seven years major advances in the liberal crusade to bolster economic security for the poor and middle class. They think the progress on climate change is real, and likely to beget more in the future.

It seems that many of the Sanders supporters hold a different view of President Obama which is also a leading reason why Sanders is not exciting African American voters. Again, it may be difficult for Sanders to appeal to African American voters when one of the premises of his campaign is that Sanders does not think that President Obama is a progressive or a good POTUS.

Again, I am not ashamed to admit that I like President Obama and think that he has accomplished a great deal which is why I do not mind Hillary Clinton promising to continue President Obama's legacy. There are valid reasons why many non-African American democrats (myself included) and many African American Democratic voters are not supporting Sanders.

I understand why Sanders supporters dislike talking about demographics but the fact remain that Sanders supporters tend to not like President Obama and that dislike affects the amount of support that Sanders is getting from certain demographic groups.
