Can you still adopt if you have had parental rights removed but for reasons other than child abuse?
This is something that would be dealt with on a case by case
basis; start by talking to DCF (or whatever it's called in your
area: department of children and families) and get information
directly from them.
I don't think that they will allow anyone to adopt that has had
their parental rights taken away from them. Even if it was not for
abuse, then it could have been for neglect.
