"I'm stating that a person WITHOUT symptoms is MORE likely to expose someone vulnerable to the virus to the actual virus."
ok, lets work with that.
a person who is asymptomatic has a much lower viral load..... do you understand that the degree of illness is related to the reproducibility of the virus?
and the vaccine induces a more rapid immune response than the unvaccinated person?
therefore the unvaccinated person will have a higher viral load than the unvaccinated person
the person with a higher viral load presents a greater probability of resulting infection to another person
therefore the vaccinated person presents a much lower probability of resulting in infection of another person than an unvaccinated person.
