Genocide has different meaning to different people. It is thrown around like Kool-Aid or EC.
In 1948, the United Nations Genocide Convention defined genocide as any of five "acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group". These five acts were: killing members of the group, causing them serious bodily or mental harm, imposing living conditions intended to destroy the group, preventing births, and forcibly transferring children out of the group. Victims are targeted because of their real or perceived membership of a group, not randomly.
Have individuals claimed Israel has committed genocide, yes.
Does people on the beach show they have not committed one or more of the five acts, no
