I know the difference between journalism and a slogan.

The difference between literature and journalism is that journalism is unreadable and literature is not read.

In any art, you don't know in advance what you want to say - it's revealed to you as you say it. That's the difference between art and illustration.

I understand the difference between journalism and scholarship that comes 20 years later.

The slogan is so vague,

I don't like it when people don't know the difference between 'their', 'they're', 'there'.
