Passion of writing or painting or singing is not related for proving. These are the feelings of an artist. Atleast he is able to express his thoughts and opinions of some situations. Don’t insult an artist because he can able to understand and reading the feelings of heart.
If an author shared his feelings through his writings it’s not that he is insane, but he so emotional of that situation. Every human will have 2 sides. But no one can show there 2 sides because they don’t have that much dare to show there 2nd side. Only an artist have that guts to show every side of his feelings and he can express.
Encourage the artist to give the world new crisps.
