Yes, everything you've said is opinion and opinions differ. Unfortunately, you've been unable to support your opinions in any way. There's no need to apologize or beat yourself up over it. You're not the only person who believes in things they don't understand and and can't explain. Thankfully, the people who are responsible for regulating what we're allowed to eat are much more rational (and much less emotional) than you.
As always, you are so right. What do you know about irony?
