The heart of debate is the ability to respond to opposing views. Knowing when to fully rebut, fully agree, or partially agree, and expressing each appropriately, is the mark of an expert speaker.
Rebuttal Expressions
When rebutting, point out the flaw in the logic rather than attacking the person. Use patterns such as "κ·Έ λ Όλ¦¬μλ ν κ°μ§ λ¬Έμ κ° μμ΅λλ€" (there is one problem with that logic) and "κ·Έ μ£Όμ₯μ ~μ κ°κ³Όνκ³ μμ΅λλ€" (that argument overlooks...).
I share the principle, but I differ on the scope of its application.
Conceding then Counter-Arguing
Experts first acknowledge the valid part of an opponent's point, then pivot to the core rebuttal. The flow "~μ λΆλͺ λ§μ΅λλ€. λ€λ§ ~" (that is certainly true; however...) is the most effective.
π‘ Tip: Partial agreement is one of the most persuasive strategies in debate. Acknowledging the valid part of an opponent's point first lends greater credibility to the rebuttal that follows.
