You don’t know what you’re talking about. Keep your opinion to yourself.
There is a thing we love to tell people when we strongly disagree with them, but wouldn’t dare tell someone who agrees with us completely. It generally goes that if you speak your mind often enough, you fill find people who will tell you to keep your opinion to yourself. They are literally requesting that you simply to not speak what you think at all on the matter. Find somebody you disagree with enough, and you might do the same.
