I was attempting to point out the grandparents error by elaborating their argument in an outlandish way. I clearly failed. Sorry about that.

It's the full stop after "I agree." that makes the statement lose your intention.

You're completely right. I was on the fence as to whether it was sarcasm or not, decided not based on "I agree.".

Well done, internet intention interpreter dolessdrugs.

For the record, I caught and appreciated the sarcasm -- but it's very difficult to pull off in writing.
