Basically this.

I know several people who were… uneasy with the destitution and humanitarian issues they saw in Gaza, but supported Israel overall because before Oct7 the news was only “Hamas fires 16 rockets against Haifa” and Israel wasn’t going wild carpet bombing

That ambiguous support is gone now that Likud & the coalition have gone full mask off. They’re not pushing BDS, but their view has fundamentally shifted on this conflict over a matter of days and weeks
