How do you describe yourself?

Hello everyone, hope you can help me. I've found myself in an exchange of views with someone (suspect neurotypical) over the use of the term "autie". I'm sure I've seen it used in a postive way by #ActuallyAutistic people on Facebook and Twitter, to describe themselves and fellow autisitic people. However, this person claims that some autistic people find it hurtful. But I would like to know what do you think of it?
