The most important point in arguing is to never follow the other person's line of thinking or logic, as many people tend to get provoked and then sidetracked by the other party.
For example, someone insults you, "You play basketball like XXX"!
To prove you don't play like XXX, you might try to excuse yourself, claiming that you play beautifully, and may even want to showcase your elegant layup.
This traps you in a cycle of self-justification; arguing is never about proving yourself right but about attacking the other person, and it should be an attack without any rationale.
So, the correct approach at this time is to ignore whether you play beautifully or not, and not to get involved in the trivial dispute over who plays more beautifully, but to directly launch an attack on the opponent.
If you know the opponent's weaknesses, it's even better to focus your attack on those weaknesses.
