After the plaintiff and defendant exchanged several profanity-laced emails, a Denton County lawyer has decided to dismiss his $100 million defamation suit against an online critic who allegedly called him a “Nazi” and “white supremacist” in internet postings and caused the attorney to lose his job at a law firm.

Attorney Jason Van Dyke filed the defamation case against Thomas Retzlaff in a state district court earlier this year. But Retzlaff later removed the suit to federal court and moved to dismiss it under the Texas Citizens Participation Act, an anti-SLAPP law passed by the Texas Legislature in 2011 that allows judges to quickly dismiss cases that infringe on free-speech rights, and forces a plaintiff to pay the defendant’s court costs.
