I have a black and white perspective on some things, but not all things. I can work on specific things, but then moving on to the next thing it's back to square one. It's actually frustrating because it makes it difficult to see why someone would disagree with me on a particular point.
I find it interesting on here that disagreement is sometimes characterized as black and white thinking, whether or not it is - or whether or not it's not a matter of being unable to see someone else's perspective, but finding that perspective extremely disagreeable - say, for example, debating the worthiness of my humanity on the basis of traits such as my sexual orientation, gender, economic class, disability, etc. I don't see much value in accepting the other person's perspective as valid, although this does not mean I am incapable of understanding it.
I do try to be open to what other people say and incorporate that into my worldview if possible, or at least understand it.
I also have trouble with "maybe" and actually have trouble with "I don't know." I would so much prefer "let me get back to you." A month or so before I was really looking at the idea that I was autistic I had a near-meltdown over a conversation with someone who answered me, "I don't know," and "maybe" as well as a third indeterminate answer that I could not interpret. I usually guess "no" when people do this, although of course that isn't always the case.
