I work in the office for a care agency mate. Does he not have a social worker or a CPN who can advise? As someone with mid to late stage alzheimers would normally have one of these. Maybe look at The Dunes in Redcar or Barnaby House in Eston. I would also consider what JaenBoro has said.
So for example - you couldn't understand, the Russian public celebrating when Stalin died? Obviously this guy wasn't Stalin but 100% a horrible war criminal.
I'm not on the right and while there obviously will be a fair bit of this, but to simply chalk this up to general bigotry overall is a wrong and narrow minded view also.
