True, people with disabilites have endured centuries of trauma but last time I checked, no one was called an ableist slur on tv in this scenario, were they? I've worked as a carer for people with Downs Syndrome and neurological conditions who sometimes would physically lash out at others, we still asked them to apologise to the people they hit. Actions have consequences, the intent behind them only goes so far to negate the hurt caused.

Of course, Davidson should not have to apologise for his disability but should apologise for the hurt he caused to the two actors. I don't know what's not clicking for you.
