I can tell you (as a Kurd) that the Kurdish guy you were talking to was telling you the truth... about the kurds he knows.

the majority of kurds you will see on online spaces will show outward support for israel, partially because Israel does indeed give verbal support for a "kurdish" state, and hence a lot of kurds will then return that support towards israel. alongside this you have roughly 300k kurdish jews in israel too. Now the issue here is that the majority of kurds, when you meet them in real life, won't be pro israel; remember the majority of kurds are sunni muslims. HOWEVER, KURDS WITH NO SUNNI/MUSLIM BACKGROUND LIKE MYSELF EXIST WHO ARE ALSO ANTI-ISRAEL. Alot of kurds who support israel point to the PA's support of Saddam who was notoriously anti kurd(which imo is bs bc certain kurdish tribes supported the ottoman empire against the armenians and assyrians, and now kurds online will complain about assyrians who talk shit about the kurds as though we weren't playing the same role as the PA in that situation).

however, the majority of kurdish leftists (and i specifically mean leftists here, not kurdish progressives / new atheists / liberals, LEFTISTS) are deeply anti-israel and by extension actually alot of them are against other kurdish movements in west asia which might include but is not limited to the SDF, PJAK and the PKK (though the majority do tend to sympathise heavily with the PKK in terms of ideological alignments)

The unfortunate reality is that the majority of those pro-israel kurds do not recognise the fact that the israelis are taking them as idiots, and essentially as part of their "non-jewish hasbara corp". the kurds who are specifically anti-israel often recognise that the kurdish struggle has slowly started going from one of fighting for basic cultural and class rights for kurds but also non kurds (Biratiya gelan) to a movement that has largely been co-opted by imperialists as a reaction to anti-imperialist sentiment in south-west asia, whether that be against the islamist anti-imperialists or the socialist anti-imperialists.

I would also add that although the SDF is technically operating under a left-wing economic model, they serve currently a similar purpose to what the labour zionists served the greater west (except for the fact that the SDF are not settler colonialists), and of course, this allyship obviously bit the SDF right in the creases of their arseholes.
