Is this what we want?

As has been in the news recently, there was an explosion in New York City. When such an event occurs, you think people would unite and hope that those injured are okay, correct?

Not if you're a die-hard Trump supporter. Apparently, the appropriate response is to celebrate and declare the explosion a victory for him, as it shows he's correct about wanting to ban Muslims (this was said even before anyone was arrested in connection with the explosion), why refugees should be banned and that it's evidence that President Barack Obama's and Secretary of State Hillary Clinton's policies in the Middle East have "failed". (I'm not sure what policy they want in the Middle East - expanding drone strikes or sending in the army? Great way to create more refugees and more enemies.)

Is this what we want? People who openly cheer others being hurt (in this case, Americans celebrating violence against other Americans) because it will lead to their political "side" winning? How is this positive?
