Depends how it's phrased. If someone says "I like liquorice" then I'm not going to downvote. But if someone said "liquorice is the best food in the world" as if it was a fact, then I am going to downvote. If OP said "It is my opinion that Jupiter was created by god" I would not have downvoted. But it's his stating it as a fact which is making me downvote.
