In response to occasional crimes by a few Muslims, the US wages actual war against lots of Muslims.

I should point out that the guns used by Malik and his spouse were not lawfully purchased in the form he had them, and a stricter system of gun control could have made them difficult for him to get.

Because the US is waging actual war, its innocent victims greatly outnumber the victims of Muslim terrorists in the US. Americans are much more likely to be killed by thugs than by terrorists.

Christianist terrorism against US abortion facilities is a more serious threat because it is concentrated against a few. If you are an abortion doctor, that danger is large.
