That is just absolute horseshit. That conclusion doesn't follow from the premise in any logical way.
Genocide has various historical definitions, but they usually surround efforts to destroy a national or ethnic group. Indicators of this include mass displacement, ethnic cleansing, mass abduction of children, etc. The IDF is actively engaged in quite a lot of these according to all reputable international observers. And saying this is just a "fucked up war" ignores the undeniable fact that a lot of this-- mass displacement, a two-tier legal system, common extrajudicial killings-- were ongoing even in times of supposed peace.
