In all fairness, there probably is some bias towards vision. More exactly, there is bias towards things that are easy to study. Vision and audition are easy to study because screens and speakers are widely available. Touch and proprioception are harder, but still common. Smell and taste are rare. So your point is far from crazy. However, there is sufficient multi-modal evidence that I don't think our current theories of access consciousness are mere visual artifacts.
