Patronising the elderly is no different from the way men used to patronise women. 'Don't worry your pretty little head', OOh that is much too difficult for girl like you to do'
Also all said and meant in the kidest of manner, but demeaning and diempowering all the same.
Women could not gain respect, while they still had to live and work with the attitudes that lay behind these mild and mindless comments.
It is exactly the same when you get old, the remarks themselves are trivial and can be shrugged off, or they can amuse us, but the attitudes that lie behind these trivial remarks are dangerous to us and our lives, it leaves to our lives being seen as less valuable than others.
Would there have been fewer deaths among the elderly if COVID in that age group had been treated seriously and not just (shrug) inevitable. We know that older people get poorer treatment for heart attacks, strokes and caancer. It takes longer to get tests, they do not offer treatments that are known to be efficacious, or not till much later in the illness.
All these thing rise from a general societal attitude that old people are less intelligent than other people, a drain on society, and just standing around waiting to die.
It is like Chaos theory that shows how the flapping of a butterfly's wing in Indonesia causes the hurricane in the north atlantic.
The very old person, otherwise fit, dying from a minor stroke, because they were not given the same instant treatment that other stroke victims get, starts with the odd patronising remark made to an elderly person by a shop assistant.
