She was not just replying to comments about her child, it is the whole special needs community that she stands up for. When has it ever been ok to make fun of anyone with special needs. Didn’t your mom ever smack you up side the head and tell you not to stare just because someone else was different. Get real.
Sounds like she would make a good spouse to a president. She could then adopt a really important cause like children being too fat or a cause like making people aware that it is not cool to make fun of mentally handicapped people.
