Debate
Debate is a really good way in which we can formally express our views on certain subjects, as well as hear from others with different views on these subjects. The result of debate for most people is either a reinforcement of our existing perceptions, or an adding of validation to alternative arguments, which can then in turn cause us to question our own stance. It is important to challenge our views to ensure that we are on the right path, and to make sure our perspectives are multi-dimensional. If we perform well in debate, and eloquently put our views across, we can even change the minds of others. There is great power in this, and we can use this to our advantage as members of marginalised communities.
