The left is angry because they feel that their worldview and values are being challenged or threatened by the right, who they perceive as ignorant, oppressive, or immoral.
As well the left is angry because they are influenced by postmodernism, which rejects objective truth and reason and promotes relativism and subjectivism.
This leads them to be intolerant of dissenting opinions and to resort to emotional appeals or personal attacks.
The left is also angry because they are frustrated by the lack of progress or change in the issues they care about, such as social justice, climate change, or economic inequality.
