If people won't take the peaceful protests seriously the protestors that don't get maimed, murdered, or imprisoned will, almost certainly not give up. Instead, as the movement grows, because the problems are getting worse and the cohort growing in number the protests will inevitably get worse until the movement is crippled or succeeds one way or another. Destroying property and looting is a common theme in successful protests. Your casual contempt of the plight of the poor and minority and ignorance of this is telling but not surprising.
