No, still doesn’t change what’s true and is reality.

its unfortunate left wing bias in mainstream media has atrophied the ability for any reliable news media to exist with extensive coverage and neutral reporting. (not unique to the left, right wing actors can do just the same it’s just right now left leaning political actors control most of legacy mainstream media)

Foreign actors are definitely taking advantage of that to fuel tensions as much as they can. Doesnt change reality tho.

That UK has a severe free speech issue and two tier policing, one for native brits(the lower tier) and one for politicians and favoured religious vote banks.

Even if mainstream media had a left wing bias - which is a big stretch in the UK given that it's mostly owned by Rothermere, Murdoch, Barclay and Marshall - why would that prevent reliable and neutral media from existing?
