Thanks to @agteien for this:
I quote a bit from the beginning:
“But we’re not all like that!” We’ve all said it, haven’t we? Read or heard something that seems to criticise a group we belong to or feel part of and said, “But we’re not all like that!” I know I have. It’s instinctive. Especially so for those working in social care or the NHS, perhaps even more so for those working in mental health which seems to get criticism from every angle. There are many committed, hard-working, professional, compassionate staff who do the best they can in difficult circumstances, make a positive difference to people’s lives and do a really good job.
So when a dedicated GP or mental health occupational therapist hears a story on the news about terrible care in a service elsewhere, he might say, “But not all of us are like that!”
