People as individuals, may read some papers and rate them more reliable than others, they may bend to papers that supporttheir views, but in the end you get to the final point between people and that is that those who most avidly support one of the two main parties hold those who vote for the other in utter contempt and see them as vile and contemptible.
I have said before on here that IMO the ideas of 'left' and 'right' are very broad generalisations, and often confused. Most people who are not extremists will have some views that others would consider to be on one side of this imaginary divide and some that would be thought to be on the other.
Also, someone can think differently from me without my thinking they are vile and contemptible. I have only ever voted Labour, but have friends who vote very differently, across the spectrum - some even voted for Brexit!
. I can disagree vehemently on some things, but like them as people and agree with them in other areas.
Like most people I have lines in the sand, but they aren't over the L/R axes of economic policy or state intervention - they are much more fundamental than that, and it is rarely that I come across people with views that would make me actively avoid them for holding.
I don't often come across people who are so entrenched in their views that they can't rub along with others either. It's different online, as we don't have the social need to get along when the conversation is over, and we don't have the shared cultural norms (for want of a better term) that brings people together in 'real life' in order to have political discussions in the first place.
