It's so hard to criticize your own, isn't it? People put up with things from friends, family, political party, religion, whatever they'd never accept from anyone else.
Good cops who won't rat out bad cops are a great example. It gives everyone involved a bad name. People who claim not to be racist but vote for Republicans are another.
If someone votes for racists and tolerate it in their party, aren't they racists too?
It's also interesting how many Christians hold Muslims to a different standard, holding that whole faith responsible for the actions of its extremists but not their own.
I think there might even be a Bible verse addressing this issue...
