You said that peaceful protest doesn’t work as well. I was addressing that since it is so inaccurate I felt compelled to point that out.
Murder is always bad, killing a person is the absolute last option and only to stop them from killing another person immediately, not theoretically, not in decades. If we aren’t able to have moral means to achieve moral ends we don’t deserve moral ends.
Your best bet is if you care about these issues is go get employment in the waste/pollution/garbage/environmental sector. Plenty of jobs available, you get to make a difference, the pay is pretty good, and you don’t fucking murder people by blocking ambulances. I have shitty days at work like everyone else, even a shitty day I know I made the world that much cleaner and it was worth it.
