Well, here's one example...
In Justin Baldoni's book, "Man Enough," he encourages men/boys to "be flexible" -- particularly in regard to heterosexual spousal/dating relationships.
For those of us with ASD (Autism Spectrum Disorder), it isn't an "on/off"-switch. We can't always just "be flexible" on command. And, even when someone feels that we aren't "being flexible enough," our behavior could be for valid underlying reasons (specific to the individual) that they just aren't aware of.
This is unconscious ableism. It isn't being done with intentional malice against us...but it's still operating under the framework of neurotypical people expecting neurodiverse people to behave according to their standards/norms.
