Please assume good intent. I don't believe the poster jumping in to attack the (ridiculous) idea that disabled people are inherently less attractive is trying to say that being ashamed of a disabled partner is inevitable or excusable.

Yes, thank you. I was speaking from experience: I have a disability myself (though I don't look it), so I've felt the stigma first-hand, but I don't think it's universal.

I've had partners who were ashamed of me before. My current partner isn't but still gets grossed out when my joints dislocate, though they know it's bad and try to help me when that happens. It varies.
