I'm not defending anything. I simply think that things need more evidence than a prejudice and a BBC article that is then misrepresented to make generalisations and accusations.
I accept that Loo's comments can easily be criticised for making assumptions and engaging in generalisations.
But you are guilty too - focussing on the 'majority' of cases being historic - 1870-1930 and that many appear to have been deaths from common natural causes provides the impression that you are assuming that all were - i.e. generalising.
So you both appear guilty of the same 'crimes'.
If what we have read is correct there appear to be about 400 bodies, while the care home itself only indicated that, according to their records, only about 150 bodies were buried there. That's a big difference and if nothing else we need to understand why there is such a huge discrepancy. There also are strong accusations of physical abuse in the home and many of the deaths don't appear to have been appropriately recorded or investigated. That includes the 1961 death discussed in the article.
It may be the case that none of the deaths was suspicious but given what we know we cannot assume that to be the case and a serious investigation needs to take place to determine whether or not serious crimes may have been committed at the home.
