A 41 year old engineering graduate student has hired a lawyer to possibly sue history blogger Bitch PhD--an anonymous blogger--for libel. Paul Deignan and Bitch PhD tangled over the question of abortion on their blogs and comment boards. Threats of a lawsuit followed when University of Northern Iowa history professor Wallace Hettle complained to Deignan's advisor about the tenor of his posts on Bitch PhD's blog. Deignan says he is considering suing both Bitch PhD and Hettle.
