Opinions are not, "wrong" they can be misguided. If a person has never taken Physics, they don't know the definition of Red Light, so they don't know that the actual physical color they think they're seeing, is not important, the same wavelength is going to everyone else that is going to them.

The creation of misguided opinions is something that can, if they're opinions that are based on the physical world, teach someone. Example, "I think the sky is Red, because I think I'm a bit colorblind." Tavrobel freaks out at the bad physics just uttered, now someone better knows the definition of color. But what that person thought and imagined can't be called wrong, because without the ability to think outside of the box, without the ability to think it terms that don't seem real to others, our world would be different. Einstein is the example I'm hinting towards.

Then there's just opinion...y opinions. Like "I think this food is the smurfing dude". Don't try to seriously quantify anyone as truly right or wrong.

You can see green, and it will still be red. Read the goddamn definition. 500-700 nm from trough to trough.

If you're going to rage on about higher level physics concepts, use the definition of a kilogram, okay? It's a friggin' block in the middle of France.
I love people who love Physics enough that the discussion of it makes them angry.
