It never made sense really, semitic people are not relegated to jewish people, they are a minority. Arabs are all semetic (Iran eastward are "aryan.") Descended from the phoencians and later the carthaginians and the like.

It's not meaningless, but consider the source

As a Jew, I've definitely experienced antisemitism. I've also been called antisemitic myself (almost always from boot licking Zionists), but I can tell the difference between brainwashed Jew hating fascists and brainwashed Zionist fascists

It certainly is annoying, because antisemitism is a real thing. Look at the mass shooting in Pittsburgh and the one in Australia
