Prominent people in BLM made it clear that they didn't condone the violence being done by a small group of people.
The Palestinian protests can't denounce Hamas, a group that murdered over a thousand people in the most brutal ways imaginable. Which is far beyond some looting that occurred during the BLM protests. While prominent people in BLM denounced the looting, we hear basically nothing about people in Palestinian protests denouncing Hamas.
Do you really think that looting is the same thing as massacring villages? If so, you may have lost perspective.
