Suppose someone refused to serve African-Americans in their restaurant because he had once been beaten up and robbed by a gang of African-American teenagers? After all, it would be " a bit insensitive" to require him to let blacks in his restaurant after that traumatic experience he went through. Furthermore there are lots of areas of town that white people can't go into now for fear of violence. It's hardly fair to expect us to let blacks into "our" parts of town, when we can't go into "their" parts of town. And don't tell me that these teenagers were not typical blacks, that's just liberal propaganda. If you read the paper, you'll see that there are lots of black people who do things like that.
Do I need to spell this out? There is no significant difference between this example and the reaction to the Cordoba center. It's bigotry, pure and simple, to blame and discriminate against individuals because of the behavior of other individuals who happen to share their religion, skin color or ethnicity.
