A: Why didn’t you join our discussion at the meeting?

B: I don’t mind the cut and thrust of argument, but I prefer friendlier and more relaxed conversation.

Note: This idiom refers to “different opinions expressed with enthusiasm” or used as adjective, “a lively, aggressive manner.” To “cut” is to slice or slash. To “thrust” is to push and stab. “Cut” and “thrust” are originally words to describe the two most common movements in fencing and sword play. Metaphorically, when we talk about the cut and thrust of something, we mean to address the exciting and challenging part of it, the quality that makes it different and demanding.
