Of course it's not genocide(I assume you're referring to Gaza like most others who make this claim), there is a war against an organization(Hamas) that embeds itself within a civilian population(which is a war crime).

> Israel is not murdering innocent civilians on a grand scale, be that by directly killing or by indirect ways of starving them out?

There is collateral damage(due to Hamas embedding within civilian populations) and various degrees of food insecurity, but there is no evidence of any mass starvation.
