What you say is true. There are still enormous numbers of people entering the US without problems. What's happened is an extremely low-probability event became slightly more probable, but still very improbable. Nonetheless, it's totally understandable that it makes people not want to risk it. If you liked to hike on a certain mountain and then found that, while the risk of being struck by lightning on an average day is one in 20 million, the risk of being struck while hiking on that particular mountain is one is one in 5 million, wouldn't you consider hiking on a different mountain? There's no denying the situation has gotten significantly worse, and for many people who don't have a pressing need to come to the US, that's enough to make it not worth it to come.
