No US presidential candidates are involved in genocide
While there’s a huge atrocity/humanitarian crisis in Gaza, genocide implies an intent that’s not there
Hamas started it and are the legally elected and internationally recognized government - they invaded a foreign country, killed over 1,000 civilians, kidnapped hundreds as hostages, and assumed they could just leave safely.
No one can argue the horror being inflicted on Palestinian civilians, nor the scale of that horror, but it’s not as black and white as you make it seem by throwing around loaded terms like “genocide”, nor is US directly involved, nor can we necessarily intervene in another country’s affairs
