Mediawijs translated some of their No Hate Speech tools into English:

• Ignoring hate posts is not an option! But, how can you react in the best possible way? 
  Therefor we've listed the most important do’s and don’ts in case of hate speech.
• Everyday, questions, compliments or opinions, but also spam, misleading information and even hate speech cross the internet. As an individual it’s not always clear what you can do about this. Should you react to it, ignore it or correct it? And how can you make sure that you participate in a conversation with mutual respect?
  We've created a poster with guidelines, which can help you to react correctly on social media.
• The project AlterNarrative helps to recognize hate speech (is everything offensive hate speech?) and to helps to create effective counter and alternative narratives.
  The core of the project are 5 key questions one should ask oneself before reacting on hateful comments. These are the basics for a training by Tumult, but can also be very helpful on their own.

These tools are only a few of the many tools thate where created by the different No Hate Speech Movements all over Europe. Do you want more? You should definitely check the manuals Bookmarks and We CAN! Or any of the many other publications on hate speech.
