Do you have any evidence that the denormalization of racism etc. is because of social media? Or that social media even helped? The ongoing fight to change the things you cite all predate social media by decades or more. Even with the Arab Spring, was social media helpful or just the tool used to coordinate? Would it have happened anyway without Twitter being there as a means to broadcast? A common criticism I have heard of social media is that it is so easy to just retweet/like and wave the flag that many people stop doing anything meaningful and visible outside the echo chamber entirely.
