When cars became more and more common a hundred years ago, many things had to be reconsidered and rearranged. Today the world of the internet creates numerous challenges that we have not faced before. Our child may become a victim while sitting in the safety of his or her room, alone and quiet; anonymous strangers may badmouth any of us; and the shared contents of anyone may reach thousands. Many parents and teachers would be likely to respond to the dangers of the internet with prohibition. However, making a responsible decision through informing ourselves of the potential gains and risks is a much better solution than prohibition. Because the same way as there is no gain without risks, there are no functionable democracies without curious and responsible citizens either. Thanks to Hope to the Children Association (Reményt a Gyermekeknek Egyesület), Bookmarks (Böngésző), a publication that supports the work of teachers and other youth workers by providing information on the theory and practice of recognising and handling internet harrasment and hate speech has been published in Hungarian.
