I see where you're coming from but you're incorrect. It's not about sweeping things under the rug. It's the tarring of all 'muslim countries' (whatever that means) with the same brush, as though we ourselves in non 'muslim countries' don't have the same problems.

It's the perpetuation of all muslims as evil savages that leads to the idea that they're somehow subhuman. Just because some of the 'other' may (or may not) talk differently, have a beard, dress differently or not drink alcohol doesn't mean that they aren't people. And yes, all countries have their problems with human rights abuses, people being attacked for various reasons and so on, but it's important to separate the religious element from the culture of individual ethnic and tribal groups.

To tar all 'muslim countries' is to tar 'muslims' as being part of that, and that's a slippery slope some seem to be further down than others.
