Are you ok with someone who was abused by a parent dating your child?

My step dad was an abusive man. He wasn't kind and for that reason is no longer apart of my life. My mother in law recently told me that she didn't believe I was good enough for her step-son because I was abused. She said i should understand now that I'm a mother why it is that she wouldn't want him marrying "someone like you".  (Someone who had been abused as a child.). It isn't the first time I'd heard that I was damaged goods and wasn't good enough to date certain people. So I thought I'd see how common that is.
