Yeah, he thinks disability law means he has special privileges. He also thinks it means he can't be held accountable for anything he does while "anxious." That's not how it works. If I'm a boss, I can't fire you just because you're alcoholic, as long as you do your job. But if you come into work drunk, I can fire you, alcoholic or not. He wields the discrimination accusation like it's a magic bullet and it's not. I've seen people with worse disabilities (like having no legs) than Russ who still manage to behave like civilized adults. Something had to have happened in his childhood to give him a sense of entitlement so massive it could pull the moon from its orbit.
And I'm sure someone in his past (like a teacher or speech and language pathologist) said that just because you have a disability or anxiety/depression, doesn't give you the right or excuse to wallow in it.
In self-contained SPED classrooms and with SPED support staff, the rule of the day--every day--is to get BETTER. Recovery and Independence are the order of the day--every day. And while you are working towards recovery and/or independence, transitional plans are supposed to be made with appropriate supports/step-down supports to encourage and grow the individual's efficacy.
Problem is, there are too many educators, administrators, support staff, and mental health professionals who like to say things like "I'm not making excuses for his behavior, but..." And then proceeds to make excuses. It's more common than people think, and I suspect the butternut squash had plenty of adult excuse makers staning for him.
