Some opinions aren't worthy of being corrected. When I am working on a problem of measuring the magnetic field throughout a detector, and someone randomly walks up to me and says, "I don't think what you are doing makes any sense, since magnetism is merely a work of God, and all your science is bollocks" - I won't be "correcting" him, I will just ignore him and spend my time in a more productive way. If I bothered with "correcting" everyone who comes up with random stuff on the fly, then I would never have done anything at all. If you want to develop your own theory and discuss it with others - sure, go ahead... But if you just make things up without any reasonable basis, then discussing it with you is pointless.
