I think the problem lies in a remarkable decline in people's capacity to consider different 'formulations' about what is going on.
We are exposed to different information. We also have biases that lead us to notice, attend to, and process information/content differently. We therefore come up with different conclusions about what is happening, why it's happening and what needs to happen.
People on the right and the left have been seeking to control the information/ content people can access (including individual expression of views), as opposed to engaging in the substantive arguments being made. Politicians have been able to make a lot of headway through controlling narratives. It is commonplace these days for politicians to tell a story/ hold a line and just repeat it.
When it comes to the left, I think they are heavily influenced by the idea that discussion and critique are used as a mechanism of oppressors to sustain power. However, this idea arises from an incontestable / circular theory - which is why they view it as a fact!
We really need effective systems that hold politicians to account for the proposals and decisions they make. Proper scrutiny needs to be applied so they can't simply control a narrative and drive it forward (with the added bonus that this is what justice looks like).
What infuriates me about 'the left' (which is where I sit politically) is their refusal to accept/admit that they are thwarting justice, democracy and equality.
We did not need to take votes from men to give them to women
We do not need to reduce the quality of education for white kids to improve it for black kids
We do not need to take away single sex facilities for females to provide facilities for trans identifying males
We do not need to remove the expression of thoughts and ideas of one group to enable the thoughts and ideas of another's to be listened to
