You can tell the difference because when it comes to opinions, people don't typically fly off the handle.
An opinion is whether mustard is a valid condiment for a hot-dog -- and of what type. It's whether Rush has put out a good album since Grace Under Pressure. It's whether pineapple belongs on pizza.
An opinion does not cover whether life-saving treatment should be provided to infants, or if a certain classification of human beings should be denied basic rights. That's just hate and fear masquerading as a 'social issue'.

Unrelated, I think I might have a cappuccino after lunch today.
