What are you basing that on?

The linked article roundly suggests that the protestors in question are staunchly anti-war and largely a non-zionist cohort.

From the outset, we protested because the consequences of this unlawful war were clear. It threatened to ignite a regional conflict that would claim countless civilian lives across the Middle East. To us, its stated objectives echoed past catastrophic Western attempts at regime change that produced nothing but prolonged instability and devastation.

Prominent figures of the Zionist left like Yair Golan, and members of anti-government protest groups like “Brothers and Sisters in Arms” (who previously declared their refusal to show up for reserve duty in protest of Netanyahu’s judicial overhaul) failed to show up for a simple reason: They do not oppose the war. The sobering reality is that, beyond a handful of Palestinian and non-Zionist Jewish MKs, there is no genuine parliamentary opposition to the war.
