I wonder what your opinion would be had you spent several decades doing so.
I used to work at a children's hospital and I can say that any argument you can come back with relating to 'inconvenient' will be very vocally trumped by the tens of thousands of families out there with special needs children.
I wouldn't waste another keystroke making an argument against raising a special needs child, the track record of the families that have done it successfully totally invalidates any argument made by someone who has never gone through it.
