@Ooogh's comment is right on the money, however a "critical mass" (a proportion of SNAers, as well as people of all other walks of life everywhere) either do not see it that way or do not realise the nuances.
On top of that - people see what they're already familiar with - physically. Things we see are only 20-40% data that we obtain via optic nerve/eye/pupil/outside world 'in real time'. There is about 60-80% of the content that's reconstructed/interpolated in the visual cortex (brain) - based on the things we've already learnt/seen/experienced previously. I think this is reciprocated in the thinking/opinions/attitudes accordingly.
Hence personal viewpoint/opinion is so over-appreciated and the point of view of others that contrast/contradict our own ignored/belittled/denigrated - more or less readily, with more or less zeal depending on how close to the bone the issue cuts.
