Gertrude and the Trojan Horse

Gertrude always loved trolling the trolls. In the good old days through editorials in the papers. In recent years through the comments sections on online articles.
Nothing beats the pleasure of watching the bigots and jerks of the net scramble to agree with Gertrude's fake personas and shoot themselves in the foot as they invariably show their true colors or contradict themselves.
With her granddaughter's invaluable help on navigating the dangers of the net, Gertude fights the battles of those who are not as lucky, right from her late husband's too-large office chair.
