Straw man.
Please point out where I stated, or even implied, the speaker or author doesn't take the audience into account. You are intentionally misrepresenting my argument to support your statement.
I'm not 'intentionally misrepresenting' a damn thing. If there is a gap in our understanding of each other, then fine.
As to my meaning, I was attempting to interpret this;
By artison, I'm guessing you are making an analogy for the speaker.
The speaker is solely responsible for what is said, not what is understood. Reaction is exclusively on the audience.
Preemptively, if room is left for interpretation, it's on the audience to ask for clarification. Their choice to do so or not falls on them.
This reads as if the sole responsibility of a speaker is to speak. That they bare no responsibility for the understanding of their audience. Equally, it suggests that the audience should ask for clarification if they do not find clear meaning.
This is simply wrong, in all sorts of ways.
As a teacher, my audience was paramount in my planning, as was proactive questioning so as to determine whether my words made sense, or required further clarification and contextualisation.
Any assumption that it's to the audience to seek clarification assumes that the audience is capable of determining when and where they have misunderstood intent, and further that they are able to frame effective questions to address this.
I have no idea why you believe this to be true, and allow for the fact that I may be misinterpreting your intent. So...as your 'audience'...could you please clarify what you mean, if I've not got the gist of it.
