You've reacted to her, which is just she wanted.
A troll feeds of negative feedback from annoying people (such as e mails complaining about what they've said in an article)
No feedback = no food = sad troll
.
"YOU B@STARD" = Dinner Bell = Trollerlicious
e mailing this woman is just giving her the attention she craves and the vindication she needs.
IGNORE HER.
