In this case, if you're a white person, silence IS tantamount to tacit approval. I'm sorry, and folks can be upset with me all they want, but if you look at the events that happened this weekend and can't even make it to your facebook to post a "Wow, that's fucked up" status, then you've got to question yourself. I'm not saying you need to suddenly become political, but as white people we've got to denounce these people. What happens any time there's a Muslim terror incident? We look at our local mosques and expect them to come out in opposition. And they do, partially out of self-preservation and partly because they too are disgusted by the actions of a minority. Well, it's our turn to do the same, to the same kinds of people. These people do not represent us, and we need to make it crystal clear, because we expect the same out of everyone else any other time.
