It's all selfishness.
If I were born a quadriplegic, retarded or heavily compromised in any way and the docs knew that I would lead a hard life before it was too late to abort - I would want to shoot my parents in the face.
This life is hard enough being Black on top of it having special needs is a death sentence. Automatically you getting no p*ssy compared to even the average dude who gets p*ssy once a year - So you'll probably get p*ssy once every 10 years - That alone in and of itself is horrendous way to live.

This is putting aside all the other 1,001 challenges you will have to face in life socially and professionally etc.
A lot of White people be on that mess. Chinese people will abort if the kid is special needs if they know because Chinese healthcare will kill the child anyways before it reaches adulthood.
