It's about the US but the phenomenon exists in the UK too.
It is human to disagree and to hold differing opinions (it is also a human right BTW). It is healthy, useful and develops our critical thinking skills and our intellect. It helps us to apply rigour to our ideas and to sort the wheat from the chaff. It helps us to speak truthfully.
One of the reasons why we are in such a mess right now is Safetyism (see above link).
Safetyism is an approach to policy that seeks to prioritize feelings of safety. According to Haidt and Lukianoff, this comes at the cost of academic intellectual rigor, open debate and free expression of ideas. Safetyism seeks to regulate some speech or intellectual environments by minimizing the array of ideas or beliefs that make some or most people in that environment feel uncomfortable. The Coddling of the American Mind describes a rise in this approach within higher education in the United States.
Safetyism is an ideology that places self-perceived safety, especially the feeling of being protected from disagreeable ideas and information, above all other concerns. It is based on the belief that it is harmful (including, but not limited to, being medically harmful to experience uncomfortable emotions. Compared to prior generations, one of the main differences is the belief that the world should not be organized according to what is right or wrong, but according to what is safe or unsafe.^
