ご質問ありがとうございます。
「その言葉が暴走している[気がする](https://eikaiwa.dmm.com/uknow/questions/75315/)」は英語で「I feel those words are being overused」と言います。
また、この文脈を説明したいなら、下記の通り英語で説明できます。
「Words like power harassment and sexual harassment were once used as a way to protect people who were being overpowered, but it seems that now it is used for anything. For example, simply asking of weekend plans can be considered a form of sexual harassment. So I feel that those words are being overused.
ご参考になれば幸いです。
