DON'T BE ABUSIVE
Make sure your words and any content you share do not spread bigotry, prejudice, or hate, or contain otherwise unlawful content.
DON'T SPREAD THEIR HATE
Giving attention to fringe individuals with few followers and their hatred can be counterproductive. You might give them the attention and publicity that they crave.
Responding to old Tweets risks reviving a conversation and having the adverse effect of spreading hate speech to others who might not have seen it before. Timing is therefore critical
THINK ABOUT YOUR OBJECTIVES
Are you seeking to engage with the person expressing hateful speech? What for? Are you seeking to lessen the consequences of a hateful Tweet on the wider audience? Are you seeking to express support for a group or identity under attack? Thinking about your goals will help shape your response and the language you use
