Over the past few decades western society has made great strides to eradicate discriminatory practices and policies directed towards non-heterosexuals. However, we have to understand why this was even necessary in the first place. Why did people throughout the western world discriminate against non-heterosexuals? Is it inherently human to discriminate against those who are different? Or is this behaviour culturally dependent? Understanding the answers to these questions can better contextualize the currently LGBT rights movement.
