Fortunately, the wealthy aren't a race of people, so it isn't considered genocide if I begrudgingly devour each and every one of them for the good of mankind. Checkmate moralists.
Commonly genocide is associated with race in media, but the legal definition is broader in the UN Genocide Convention: "acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group". The wealthy can be easily associated with specific national groups. Check the case of Pol-Pot en Cambodia for a rather extreme example.
Let me guess, 30,000 dead Palestinian civilians at the hands of the armed wing of one of the most advanced intelligence machines in the Eastern hemisphere is just "defending their right to exist".
Take a look at the map. There's one country in the region surrounding by countries whose Jews have been ethnically cleansed. The rest of them were forced to covert during the Arab conquests that swept the land. You've got Iran, Hamas and more all openly saying they want to murder the inhabitants of that lone non Arab country so ya, they're clearly defending their right to exist.
Also interesting that you're accepting the numbers from the terrorists who started this round of fighting without question. Do you really think that not a single Hamas fighter has been among the dead? There was a Lord in Parliament the other day speaking on the civilian/combatant ratio being around 2.5:1, or about 9k of those dead being militants. Suppose you're taking Hamas numbers over the UK's on this cuz it fits your narrative?
