A single stray rocket from within Gaza killed 500 people. Israel has dropped over 10,000 bombs so far. If Israel was trying to commit genocide or intentionally hit civilians the numbers would be astronomical with regards to death toll. It is, of course, terrible that there is 7000+ dead, but a word like genocide has a specific meaning, and to use it in this context takes weight away from the word and therefore marginalizes the term being used for ACTUAL genocides.
