Today felt like the final straw when she said that she though 'half the people' in the village she's just moved to are 'on the spectrum'.
She's a very dear friend and I want to explain to her in a calm and informative way why I find her casually overusing this phrase really fucking offensive. But I'm worried I'm just going to get upset when I talk to her about it, or that she'll get defensive, so I'm wondering if it's a good idea and if anyone has dealt with this before and has advice on how best to approach it?
Background is I have an adult son with Asperger's (which is why I get bit emotional about this) and she is a child psychologist (with no specialist knowledge of autism - obviously!)
