Can I ask if you have a severely disabled relative? You don’t sound like you do. You don’t sound like you understand the issues present in this scenario?
How do you think parents like me, and others feel, reading posts saying that our children would be better off dead because you don’t like the look of their life?
What sort of condition do the children have who ‘sit in a chair hitting their head’? Are you saying that they should be euthanised? How are you in a position to accurately understand what kind of life they have? You are assessing it only from your point of view.
I am always going to call out ableist comments when I see them.
I can tell you now that if you had a severely disabled child, you’d see them as the person they are, not someone unworthy of life.
Furthermore, Disability isn’t something that happens to other people and that you are above yourself or immune to. If you or a relative became severely disabled, or had dementia, just imagine if people were having conversations like this about you or them?
