I mean I guess I don't know, and some people have disagreed with you. But how do Arabic dialects compare to all the English dialects. I mean U.S., U.K. and Australians can all understand each other mostly, but there's all those little differences too (that I personally enjoy). And even within English speaking countries there are dialects.

So are we talking almost different languages, or minor differences?

As for your other criticisms, I mean they sound a lot like English criticisms. Because English has a lot of those problems too, at a greater or lower scale I can't say. But I wonder.
