That's fair.

IMO online comments are an extremely poor medium for ambiguous comments because:

1. There's very little context provided.
2. "Conversations" typically are composed of, at most, 3-4 messages from each party.
3. It takes a while for each party to type up their response.

Due to these reasons, ambiguities should at least attempt to be cleared up with up front.

Sure you don't have to do that, but then you just get misunderstood, wasting everyone's time.

What you're suggesting applies far more easily in an IRL conversation. I can look for body language, like a smile indicating joking. Conversations take seconds instead of minutes, and there's far more back and forth
