In high school debate, DH4:Counterargument is displayed all the time by novice debaters. The phenomenon on my team was taught and cautioned against as "two ships passing in the night." Imagine a debate: each case was strong and big and impressive but the debaters' responses to one another were off the mark. Their arguments never met and rebuttals hit upon phantom contentions as each debater misunderstood or misconstrued the essential points of the opposing case/debater like "two ships passing in the night."
