I think white people are more likely to be child molesters.
Why do you say that just about white people?
Because most of the child molesters I know about are white.
It sounds like that is just your opinion though. You cannot make blanket statements about white people. Not every white person is the same.
Ok. But I still think white people are more likely to be child molesters.
Just relying on anecdotes to make broad generalizations about people is wrong. You should approach the world with a more open mind about groups of people.
