My God, Palestinians are being massacred en masse and tens of thousands of civilians are being written off as collateral. Back to reality, people - actions over words. Look at what Israel has done, look at who they've killed and how they've responded to criticism. Which word would you prefer is used to refer to uncritical supporters of Israel? Is there a word that can be used without legitimate criticism being painted as anti-semitic?
"Zioinist" has been the least offensive way of referring to those who uncritically support the Israeli state. This grouping includes fanatical Christians, obviously a good number of Jews, and a variety of other groups. Focus from those seeking to distract or obscure Israeli war crimes is on words, because they have very few actual actions to point at.
You can just say "pro-Israel"? I know it's 4 syllables instead of 3, but not bringing in a historical movement that has very little to do with the current conflict and that's widely used as a Trojan horse for antisemites to get normies on board seems like it justifies the very slight inconvenience.
For what it's worth, if you look at any of my posts, this is what I do for exactly that reason, and to avoid any connotation of anti-semitism, because it does exist, especially amongst people who want to bark about 'Zionism' without actually having any concept of what it is beyond 'Jews' which is certainly too many people.
Still think Redjohn's larger point stands though, especially with the most odious Zionists actually not even being Jewish people in my opinion but rather Christian zionists / evangelicals.
Antisemitic Zionists like John Hagee are the worst.
