That vandalism and hate is wrong regardless of the source, and most large protest movements have criminal fools like we saw in the trucker protests. Just because some BLM protestors might light fire to businesses and loot doesn't mean all BLM protestors are bad or criminals or that all BLM'ers should be written off without listening to them.
People who hid Jews from the Nazis were criminals. The freedom riders and other civil rights campaigners were criminals (and even their peaceful protests were deeply unpopular at the time). What's right and what's legal are not always the same thing and I genuinely am less interested in the fact of someone committing a crime (especially crimes against property) than I am in their reasons for doing so.
