That almost doesn't surprise me. I got beaten up by some because I was a 'reservist' wife, as opposed to an 'active duty' wife. Some freepers can be really horrible.
Yes, they can. Fortunately, they're in the minority. Bitter, unhappy little people. And they say things like that to you from the comfort of their homes, behind their keyboards. While your husband is off in a dangerous place protecting their right to do that. Aren't they lovely?
