I would urge people to be careful how much we think disabled people (might) suffer. My mom is colorblind (she sees the whole world in shades of white or black), and her vision strength is 5% or lower. She is definitely disabled and receives a pension for not being able to work. Still, she managed to build up some form of existence: she managed to start an education and became a masseuse, and she gave birth to me and my brother. If my grandma would’ve known that my mom will not be able to live on her own, she maybe wouldn’t have proceeded with the pregnancy. Then I wouldn’t be here either.
My conclusion: what do you define by disability? If it is a chronic disease which means your child will be in pain their whole life, it is very different than having a child who isn’t able to “function” normally, but isn’t inherently in pain. Over my mom I met a lot of other disabled people, and most of them have built up an existence and lead a life. My mom wouldn’t agree that she is forced to suffer her whole life.
No one is forced to bear out a child. You are not morally responsible to bear out a child, in my opinion. But we shouldn’t assume we know how this person will grow and develop during their lives.
I would like to add another viewpoint to the discussion. I am German, and for me it would heavily depend what you think while you wear it. Basically if I would ask you “what do you think about us Germans in Ghana”, the reply of the person would determine if them wearing Lederhosen is inappropriate or not. I absolutely agree with the fact that recognition of the mistreatment is the key point here; however, you often cannot recognize it from the outside. Obviously if someone wears a big MAGA sticker on their back, or a “Black Lives Matter” pin, it is easy to comprehend; but as very often in life, most situations aren’t as easy as that. Long story short, we often cannot recognize from the outside if something is cultural appropriation or not; we would need to ask the person.
