treating the subject of an essay objectively while still trying to persuade readers of your point of view?

Answer 1

Basically, present everything as facts. No "I think" or "I feel" or "my opinion" or the like. Back everything up with facts and sources, and cite all your sources. Fill in your own words to state what the facts, numbers, and trends show. But stay away from "I", "me", and "my". Just the facts and sources that were presented, and then what they mean in your translation without really saying "this is what I think"

Answer 2

Generally start with the point of view of your opponents. Then explain why those who you support feel the opponents are wrong. You can use first person ("I") in the conclusion, but avoid it up to that point.
