An indiscriminate action is done without sorting who or what will be hit, and without stopping to think about the harm. News writers use it for violence that does not separate fighters from ordinary people, or for a chemical sprayed over everything.

An indiscriminate action「indiscriminate」的行動 is done without sorting who or what will be hit做的時候沒有分辨會傷到誰或什麼，and without stopping to think about the harm也沒有停下來想後果。News writers use it新聞用這個詞 for violence that does not separate fighters from ordinary people來說不分戰鬥人員和一般人的暴力，or for a chemical sprayed over everything或是不分對象到處噴灑的化學藥劑。

The heart of the idea is “no choosing”: the person acting does not pick a right target from a wrong one. It is a criticising word in this sense — you are saying the action was careless of the damage.

The heart of the idea is “no choosing”這個詞的核心是「不挑」：the person acting行動的人 does not pick a right target from a wrong one不會去分辨對的目標和錯的目標。It is a criticising word in this sense這個意思下它是個帶批評意味的詞——you are saying the action was careless of the damage你是在說這個行動根本不在乎會造成什麼傷害。

Though actually, the same word is also used more mildly: an indiscriminate reader reads anything; indiscriminate buying means you are not fussy. The serious, harm-facing sense is the one you will meet in the news.

Though actually不過其實，the same word is also used more mildly同一個字也有比較溫和的用法：an indiscriminate reader reads anything「indiscriminate reader」是什麼都讀的人；indiscriminate buying means you are not fussy「indiscriminate buying」是說買東西不挑。The serious, harm-facing sense那個嚴肅、談傷害的意思 is the one you will meet in the news才是你在新聞裡會遇到的。

It is a formal word.
