Hahaha... bravo. It's too bad she resorted to the ad hominem path. It seems like you were getting somewhere. However, you may have actually succeeded. I've realized that people very rarely actually change their minds on the spot. They often go off and the seeds of that conversation shift around in their mind.

I've walked in on people who a year before disagreed strongly with me like she did you, only to hear them telling someone what I'd been trying to convince them.

She engaged... you made some very important points, asked some very important questions. I bet you planted some mind seeds there. ;)

Good job and welcome to steemit.
