What is Political Correctness?

Is showing respect for others as simple as avoiding certain words?

Today, many people feel out of control in the face of too much change. This leads to frustration, anger and fear. Unfortunately, the media uses this fear and anger to attract consumers and increase the power and influence of populist politicians. This diet of fear perpetuates negative stereotypes, normalises the abuse of people on the edges of our society and forms a vicious circle.
