Would you abort your unborn child if you know that he/she would be mentally retarded?

I said no in the previous thread. But this time I'll say yes, depending on how early it can be discovered.
If it can be discovered before the brain has formed properly, I wouldn't even feel bad about it.
The previous thread was about something I don't consider a big deal at all, so why go through with the hurdle of an abortion. But in this case, it would have a life long negative impact, so I would do it without regret, provided the fetus hasn't shown mesurable brain activity yet.
