It was a long time coming: An incomprehensive list of similarities between antizionism and transphobia:
An obsession with deadnames: Transphobes tend to insist on calling trans people by the name they had before they transitioned. Antizionists tend to insist on calling Jewish people who Hebrewfied their name or just changed their name to a Hebrew one, by their old name.
"If you want your own representation so badly, why don't you make it yourself?" *representation exists* "omg why do you have to shove it into our faces all the time??"
"One of the good ones", tokenization on the greater scale of hate - Queerphobes will look for transphobic LGB people to use as tokens, and nothing more. Similarly, antisemites will look for antizionist Jews to use as tokens. And nothing more.
"Your existence doesn't add up with my beliefs, so clearly you just don't exist / you're not who you claim you are"
"Actually zionism is the real antisemitism slash the reason antisemitism exists" / "Actually trans people are the ones giving a bad name to queer people"
"They are coming for us": "Trans people want to turn other people" / "Zionists want to take over the world"
Pretending to care about academic sources but actually disregarding most studies made (studies showing Jewish indiginity over the levant / studies showing the results of transgender healthcare)
"Why would you need to be defended? You are already the most protected group on the planet!"
Obviously a lot of Nazi background for both rethorics.
Pretending to care about children, oh but not THOSE children: Transphobes basic off of "protect the children" because "trans people are trying to turn out children trans", ignoring how untreated dysphoria leads to higher suicide rates among trans youth, or how a trans kid is literally murdered for being trans; Antizionists claiming to care about kids dying but cheering on when Jewish kids are being fucking murdered.
Refusing to listen to the targetted group about their own fucking experience (because clearly they're lying to achieve some secret agenda).
This might be a small thing but demonization of a flag to extreme extents: "The star of david is problematic because it appears on Israel's flag" / being "suspicious" of anything that's colored using the same scheme as the trans flag (or any queer flag in this case)
Hating on an identity trait and/or claiming it's not actually an identity trait, thinking that claiming enough that people don't exist will make it true ("Israel doesn't exist" / "there are only two genders")
Treating an identity trait as an ideology (being Israeli equating to an "evil" ideology / being trans equating to an "evil" ideology)
This one is pretty universal but telling people to kill themselves
Telling people their very existence actively causes harm
Being nosy and not minding their own fucking buisness (antizionists actively looking for posts made by Jews/Israelis to send them hate, transphobes actively looking for posts made by trans people to send them hate).
"Why make it your entire personality???"
you lot are welcome to add more
"i identify as a toaster" / "it was promised to them 3000 years ago"
"cis is a slur" / "goy is a slur"
making the targeted minority physically unsafe to the point they have to research how safe it is to travel internationally to almost anywhere (the answer is no)
"Everything they say is lies" / "Everything they say is just mental illness" to delegitimize any and all speech of targeted group.
A belief that the only good thing the targeted group can do is not exist (and equating that to kindness when confronted)
"Converts can't be ethnically Jewish" "if you can just decide to be Jewish then Jews aren't an indigenous group" / "you can't just call yourself a woman" "you're not a real man because biology"
celebrating cancer as "proving" their cause: transphobes celebrating trans women/men for getting breast/testicular cancer, "proving" they’re women/men (even tho the rate isn't really higher than cis people / antizionists celebrating "white" Israelis for getting skin cancer, "proving" they’re not indigenous to the levant (even though the rate isn't really higher than in other populations)
making up people/claim to get mad at: "there are Zionists saying 'how dare black people exist'" / "there are men claiming they are trans women just to creep in women's bathrooms"
justification of sexual assault against the "right victim" (i don't even need to elaborate on that one)
Hating for "passing privilege": The idea that Jews benefit 100% from white privilege / the idea that trans men benefit 100% from male privilege
"my grandparents are older than Israel" / "being trans wasn't a thing up until recently"
"white americans convert to judaism just to be able to live in israel (read: colonize palestine)!" / "men transition into women in order to prey on girls/dominate womens sports/etc."
treating white-passing jews like just cool white people and not acknowledging they have actual history and culture beyond just lighting a hanukia on Christmas / treating non binary people as just cool girls with colorful hair without acknowledging their actual gender identity
"you can tell them (Zionists/trans people) apart by their prominent facial features. but just to be sure i'll need to check your genitals for mutilation"
Using the targetted group as a scapegoat (by a major side of politics)
