It's not a hobby. It's not subjective. Something is either good or bad, in total (some real number value on that axis, to be specific). The kind of thing you said is literally a cop-out of confronting that. The need to put some "ist"/"ism" label on it just avoids dealing with the question entirely. That's not the definition of pacifism, what I said is the framework to situationally decide whether pacifism or something else is more ethical.
