Acknowledgment of the opposing views is called concession.
It allows you to win your argument more gracefully by first discovering the common ground with the opponent.
Find out what kind of evidence they might use, what data they might operate, or what information they might appeal to. You might even mention the actual counter-arguments before confusing them.
In other words, you are an advocate, not an adversary.
Learning how to write a persuasive essay is an essential skill that people use every day in fields from business to law to media and entertainment.
