Two options:
- You genuinely believe that all living organisms have equal moral weight. You are either a Jainist who sweeps the floor in front of your feet to avoid treading on an insect, or else a callous murderer who would dispatch an annoying human as easily as an annoying fly.
- You are a sane person who does not in fact believe that, and this comment was some sort of bad faith "gotcha".
