I am comparing apples to oranges because one is a quantifiable very real risk that we choose to take every day that endangers lives and damages the environment, and the other is less likely than getting hit by lightning yet people are arguing about saving the lives of hundreds of thousands of people because of it.You fail to appreciate that one of these things is entirely avoidable and the other really isn't. I can't reasonably give up driving. I have to drive. But this country can refuse to bring in hundreds of thousands of "refugees." You're comparing apples to oranges.
You also fail to appreciate that one of these things is possibly a personal choice. Maybe someone doesn't really need to drive. They can individually make the decision whether or not to take the risk. The decision to take in all of these refugees is a decision that is thrust upon all of us.
I'm making the point that being scared of a terrorist attack because of refugees is laughable and is not a valid reason for not wanting to let refugees in. Matters of personal choice don't matter when the argument is a bad one from the start. Might as well be against refugees because they wear green a lot and that bothers you for some reason, just as silly a reason.
