Are there people who actually deny that the baby was Jon?

I think people know it's Jon, they just think that Rheagar as his father hasn't been confirmed. And they kinda have a point there, the scene never says Rheagar is the father (though it's strongly hinted). But Lyanna is clearly his mother. Hell, Jon Snow's Wikipedia page lists Rheagar and Lyanna as his birth parents.
