Direct debating and collision of opposing and one’s
arguments to convince that one side is better than the other. State the
opponents’ arguments, state your own arguments, and (if you are doing debate competitively) state why your
argument is better.
Otherwise, rebuttals can be thrown all day, and an argument would thus
never end, or be thrown into a loop where neither side can demonstrate
superiority over the other.
Common methods include “Even if”: Even if their point is totally true,
it is still insignificant compared to the reverse side “U-turn”: Reverse
their argument, where their reason for winning is actually a reason for
losing “Weighing”: Compare the two sides’ values and factors and explain
why one should be prioritized over the other, with a metric that is
advantageous to your position. Common Metrics for weighing - Magnitude
(how many people), Probability (how likely), and Urgency (how fast).
I hate to admit this, but...
I never actually tried most of this! So it's up to your subjective free will to
decide how to do this.
