There is much more to AAVE than just "slang" There are a lot of aspects of grammar that AAVE has that other dialects of English do not. One of the main areas of study for linguists is how languages change. AAVE, having originated among slaves imported from East and Central Africa, who all learned English at the same time, is a very useful example of language change to study. Many linguists who first started to study AAVE called it ebonics, however many people who do not like black people dalso use the term to denigrate a different dialect of English, so those who studied the dialect started to use the term AAVE.

The discussion of whether another dialect is valid or not is an interesting one, but such discussions are often code for discussions about the social groups who use such dialects. I don't think you actually harbor ill will to black people, I think you just object to the rhetoric that many on the left use in regards to the topic of race.

Let me tell you about something else linguists study. It is called "code switching". Many people belong to cultural groups that tend to use their language slightly differently from the rest of society. Usually class and race play into this. For example, the Valley Girl accent also included a lot of slang and weird phrases that aren't common in standard American English. This is also true in the deep south, among surfers, latinos, and black people. Code switching is a term for when a person who speaks a version of english like those I just listed, switches to a more formal, or more standard English, that is more accepted, or just easier to understand in the context. Most black people do not use AAVE when giving a presentation. Valley Girls likely tried to use the word 'like' less when in a job interview (although I do not know how often the upper class valley girls got jobs) even people from other english speaking countries like Scotland use different words when speaking to American English speakers to avoid confusion. My point is this, African Americans speak AAVE primarily with other black people, but when context requires, they switch to a more standard variety of English. I do not think that when black people read your harsh reaction to the term AAVE that they feel more comfortable in society. Just like a white southerner with a strong accent would feel put off to be put off to see a strong reaction against academic terms used to study their varieties of English. From what I've read you don't want black and white Americans to be treated differently, or thought of as two different cultural entities. The fact is that there are some cultural differences, and attacking those differences, especially ones as personal as the way people speak, are likely to make black people feel more alienated from general society, and more proud of the differences, that you are opposed to.
