Though some will take it seriously, yes. And the republicans? it's what they make of it. Good fun shooting foreiners, I suppose that's what they consider it to be.
Though this doesn't even dignify a response, I will politely say that it's completely...misguided...to label Republicans* as people who think it's "good fun to shoot foreigners". Maybe
somebody's responsibility to protect and defend America, which might happen to include combat with "foreigners". It's fun to shoot some of them, sure, but that's because of what they do, not because they're not American.
*(By the way.
Republican = One who supports the Republican party, the GOP.
republican = One who supports a republic, which is the current form of America's government. Just like a
democrat would be a supporter of democracy, but a
Democrat would be a supporter of the Democratic party.)
