Because rather than attacking their politics, Ann decided to attack their widowhood.
Uh, no. Her attack is on their hypocritical MO:
We're 9/11 widows - GWB caused 9/11.
We're 9/11 widows - We support kerry, even made commercials for him.
We're 9/11 widows - The Iraq war is wrong.
Hey, you can't criticize our positions. We're 9/11 widows and you're being mean to us. No fair.
Speaking of crappy arguments...
No, Ann attacked their use as self-appointed human shields for an ideological cause.
