There is a frightening amount of hatred in the world and very often, physical results (signs, collisions, etc.) can be left behind as a constant reminder. Everywhere we go, we can see writings on walls that threaten someone and express hatred, just like under bridges or in buildings.

This is where Corey Fleischer comes in. His mission? Deleting hatred. And now, his personal motto has become a worldwide initiative.

Corey saw the first graffiti expressing hatred and decided to act.

Corey started his own initiative, â??Erasing Hateâ??, 9 years ago. At the time, he was traveling to a client's house on the outskirts when he noticed something painted on a concrete block. He kept walking and arrived at the place where the client was standing, but he could not forget that image.

He regretted not doing anything about the symbol of hatred. So, he came back and deleted it.

"I went back to Monkland and deleted it," he said.

Now, â??Erasing Hateâ?? combines social media and graffiti removal. People can report cases to him. Then, Corey and his crew go to the scene and take care of him.

On Instagram, Corey shares his various missions with followers.

Coreyâ??s main profession is a graffiti erasing company, so he already has all the tools he needs.

Deleting hatred is more than just a pastime for him. Fleischer says the feeling left by the disappearance of these symbols "is like drugs ... 'it's an extremely euphoric feeling. It's something I've never been able to explain."

"That's what makes me feel complete as a person," Corey Fleischer told CBC News.

Corey is now working to turn his initiative into global by launching an "Erasing Hate" app that would allow anyone with iOS or Android to report hate speech.

The app will allow users to send photos and location of hate graffiti to Fleischer, who will then use social media to find volunteers who can delete it.

He has already inspired people to dispel hatred in Paris and Los Angeles.

"We remove hatred everywhere in the world, free of charge," Corey said.

Small actions have a big impact.

Corey found a way to make an impact by using his skills to make our world a better place. As the world is going through turmoil, fighting systemic racism and other forms of discrimination and hatred, it is important to remember how we, as individuals, can contribute with our voices and actions for a better future.
