Melta - I applaud you for not getting defensive and cross with us all for disagreeing with you, which is a rare talent in life on MN.
But I am genuinely perplexed why the fact of people's disabilities is so meaningful to you that you feel such a need to discuss them?
I have a friend who I think is a bit like you. He discovered that I wore hearing aids about 5 years into our friendship (had my hair tied back, unusually, and he saw them). That was a few years ago, and ever since, he seems to be utterly obsessed with them. Every time I see him (only a few times a year as we live a long way apart), he finds a way of mentioning them, fussing over them, crowbarring them into the conversation. It bemuses me. I have worn hearing aids for more than 40 years, if everyone I have ever met was like him, I would have gone insane with boredom and irritation by now. My friend is a lovely, caring person, he just seems unable to help himself or to see the reality of what he is doing.
Can I ask: if you meet someone and notice/discover they're single / divorced / gay / childless / red-haired - or any other fact that is normal, but can be perceived or experienced negatively by some people - then do you feel the need to 'acknowledge their experience' and ask lots of 'open questions'? I am curious as to why disabilities are a particular interest.
Can you not just get to know people with visible disabilities in the same way you get to know people without them (or with invisible ones)? When I meet new people I generally just chat on neutral topics. Sometimes we feel a connection and gradually get to know each other better over time, and as that happens, we both venture into more personal territory, each leaving it to the other to broach anything they want to about themselves.
But perhaps I'm strange?
