Which of the following is the unjust or prejudicial treatment of different categories of people?

discrimination is wrong. people are people. we all need to get along no matter who we are. colour, religion etc. should not make a difference.

people who discriminates are everywhere.

It's me EMY, unfortunately it's human nature, people like other people who look like themselves. but it's wrong to treat people who don't look like you differently.

omg,i have a PhD in induring discrimination!
