We need to understand the causes of hate. In my opinion, the most important are poverty and wealth. Poverty breeds all the pathologies that make people suppressed, less educated, less cared for and more likely to commit crimes. On the other hand, we have immigrants who have a lot of money, which makes the local population jealous, who do not have this money. Another thing that can arouse hatred is the lack of understanding of differences. I think that once people understand the mechanisms of hate, they will be able to control it.
