It's normal for a child to invent an imaginary friend, but it's downright weird to invent an imaginary father?

Just because you don't like it when people use their imagination doesn't mean they shouldn't. Many people have said a problem was unsolvable until somebody came along and used a bit of imaginative thinking, and changed everything. Maybe somebody crushed the imagination out of you when you were young. Maybe you are just not very imaginative by nature. But if you don't understand something, that is a poor reason to oppress other people, mock them, or insult them.
