Opinions can be compared to a shit load of things:
"An opinion is like your jam. It's okay to listen to it, just don't listen to it on full blast (like yaoi audio)."
"An opinion is like pollen. A bee carries the pollen around everywhere, and it affects everyone. You are not a bee, so leave your pollen in your hive (that would be your brain)."
"An opinion is like your middle finger. It's okay to have it, just don't go flipping everyone off with it; that's disrespectful."
"An opinion is like a dick/vagina. It's okay to have one, just don't go around shoving it down peoples' throats/rubbing it in peoples' faces."
What about your opinion analogies?
