This kind of cliché is probably one of the reasons why college debate competitions are declining.

I think these clichés are meaningless. . .

How to deal with the other party's problems depends on preparation before the game - some say and know how to deconstruct and refute, and one relies on one's on-the-spot reaction ability - quickly analyzing the types of fallacies, and some on what the other party says. It does make sense, then just admit that the other person is right and that's it.

These are all accumulated and improved step by step in terms of strength, and cannot be solved by a few clichés. Debate is a reasonable activity, not a cross talk or a speech.
