Most people would never make the nasty remarks they do on social media to a person's face. This is because they would be able to see the hurt and upset caused by those words. On social media, the ability to see that reaction is taken away. You never know how someone would react to the nasty messages they receive on social media.
We are wanting it to be a movement, not just for a day but for generations to come - where unkindness isn't tolerated. Social media should be a place where people can socialise, network, do business and live 'their best life' without fear of negativity.
