What is the most effective way to deal with violence based on hate?

 the most effective way to deal with violence based on hate is education.
Most people hate something that they don't understand.
for example, most people hate rich people not becuase their richnes, but because deep down they wanted to obtain the same amount of wealth as them but they don't know how. Education will bring us to a newer perspective which led us to have fewer tendency toward violence
