Well Varian, I buy the Guardian sometimes, and sometimes the Telegraph, and I read some right wing publications online occasionally (and left wing ones) and I like to think that having a variety of perspectives makes me think about things more. The joys of the internet! 
However, there seems to be no middle ground on line as far as social comment is concerned. There are two warring factions - left and right and very little middle or neutral ground. The Independent claimed that but sold out years ago, sadly.
And yes, there are those who are interested in the news and politics and those that don't dwell on events and shun political discussion (quite rightly I think, for peace of mind!) because yesterday's newspapers are in the recycling and there is something new to concentrate on today.
I am not sure we influence much by bickering on-line and I always feel better when I stay away from commenting on the News and Politics forum for a few days. However, go to any site which has a comments section and most who comment seem to get very heated and passionate about their left or right wing stance. I'd like to think common sense would prevail and that there is a middle ground but right wingers are portrayed as selfish, wealthy and uncaring, or racist and stupid, and left wingers as denim-knitting, squat-dwelling communist students or middle class virtue signallers who patronise the poor because it's the right thing to do.
Slap bang in the middle is a huge swathe of people who look out for their families, care about others less fortunate, work hard, do their best and want the NHS to survive! I wish the political parties could find some common middle ground because the growing divide between left and right, fuelled by keyboard warriors after Brexit and the last election is getting silly.
PS: I agree with Corbyn about the railways.
PPS: Who admires Richard Branson? The left or the right? Or no one?
