It is clear from context that the original comment is using "indiscriminately" in a sense of "without due care; thoughtlessly". Your first reply comes across as simply contradicting it, i.e. asserting that actually these cuts were made with an appropriate level of thoughtfulness. Your point that there are criteria which are being applied is a useful contribution, but you should have expanded on this in your original comment, as it was not clear that you were reframing the discussion in this way.
