The second sentence is not grounded in reality, which is ko d of fatal to the entire argument you are trying to build on that premise.
It's not a Muslim ban. People who say that are only burning their own credibility. Indonesia isn't banned. Bangladesh isn't banned.
Libya, Yemen, Iran, Iraq, Sudan, Somalia, and Syria. Somalia is infamous for its pirates, Libya for Benghazi, Iran for its nuclear program, do I even need to continue?
It would be much easier to defend this ban as not targeting Muslims from countries that don't have the political capital to defend themselves if blanket bans like this one actually improved national security. Can you honestly make the claim that it does?

According to the guidelines, this story wouldn't normally be "on-topic", as it doesn't fit the "gratifies one's intellectual curiosity" test; it's just grist for political controversy, which HN specifically seeks to avoid.
Sure, there's currently a lot more politics on HN than normal due to current events in the US, but even still, this story doesn't add enough substance to the debate to warrant being accepted.
