What in tarnation

So, no acknowledgement of anything in their message that might be agreeable or correct?

I replied to them to call out some ignorant remarks they made. They started talking about something else. Why would I continue the conversation?

Just a denial of a tangential assumption, as if your "French nationality" were the core of that comment.

I was correcting another incorrect remark. I don't think they read what I wrote if they think I am french.

Was a pretty cogent request and the final of only 2 "paragraphs", so confused on how you might have misplaced it.

Why am I expected to respond to this person's request?
