No one is ever speaking on behalf of anyone else, unless that someone else explicitly invited them to do so. I beg to differ. In fact, it's very common for people to extrapolate based on their own experiences and speak for others whom they see as being in the same situation, whether the situation has to do with race, economic status or sexual orientation. Therefore, if people are arguing for a policy that affects many people, not just themselves, their proposal should be backed by some expertise other than just personal opinion.
