"Theories" are not "speculation".
And you're right for most theories.
But I was talking specifically about the theory of evolution, and it's generally accepted (actually it's almost a law) that evolution is made up of speculations, assumptions, unsubstantiated "facts," unobservable "observations, sub/semi-theories all topped with a sprinkle of lies as the final touch to give it the appearance of a solid theory, which is not of course.
Now, that is my educated opinion on the subject. But you may have a different take on the nebulous theory of evolution and that does not necessarily make you a bad person - only a misinformed one.
