We are asked to have opinions on far more things than we can possibly digest and reasonably evaluate ourselves. For this reason, we outsource most of our opinions to others we trust - our family, our teachers, our friends, the media, the state etc. This is the basis for propaganda, advertising, public relations and the like. The fact that repeated messaging on one side of an issue will shift public opinion in aggregate towards that side is well accepted. This does not contradict the idea that some people will reach that same position independently. It does suggest, however, that when comparing two populations the one subject to just one side of a subject since birth will be more likely to agree with that side on average than the population subject to no messaging or messaging from the other side. This fact does not actually suggest anything about correctness. As an aside, I understand this is a heated issue for many, but I'm not sure your tone improves the discussion.
