Take the reunification vs. independence debate. If a caller isn't fervently pro-independence, then he's fervently pro-reunification. Rarely does one hear a voice from the middle. This seems to suggest that many people in Taiwan support independence, which is far from the case.
就拿統獨爭議來說，打電話進去的不是急獨就是急統，少有中間聲音出現，反映出來好像很多人主張台灣獨立，和一般民調結果有很大差距。
