<human>: Answer by taking a quote from the following article:

Johan August Strindberg (; Swedish: [2strInd,baerj] ( listen); 22 January 1849 - 14 May 1912) was a Swedish playwright, novelist, poet, essayist and painter. A prolific writer who often drew directly on his personal experience, Strindberg's career spanned four decades, during which time he wrote over sixty plays and more than thirty works of fiction, autobiography, history, cultural analysis, and politics.

Influenced by the history of the Paris Commune, during 1871, young Strindberg embraced the view, that politics is a conflict between the upper and lower classes. He was admired by many as a far-left writer. He was a socialist (or perhaps more of an anarchist, meaning a libertarian socialist, which he himself claimed on at least one occasion). Strindberg's political opinions nevertheless changed considerably within this category over the years, and he was never primarily a political writer. Nor did he often campaign for any one issue, preferring instead to scorn his enemies manifesto-style - the military, the church, the monarchy, the politicians, the stingy publishers, the incompetent reviewers, the narrow-minded, the idiots - and he was not loyal to any party or ideology. Many of his works, however, had at least some politics and sometimes an abundance of it. They often displayed that life and the prevailing system were profoundly unjust and injurious to ordinary citizens.  The changing nature of his political positions shows in his changing stance on the women's rights issue. Early on, Strindberg was sympathetic to women of 19th-century Sweden, calling for women's suffrage as early as 1884. However, during other periods he had strongly misogynistic opinions, calling for lawmakers to reconsider the emancipation of these "half-apes ... mad ... criminal, instinctively evil animals." This is controversial in contemporary assessments of Strindberg, as have his antisemitic descriptions of Jews (and, in particular, Jewish enemies of his in Swedish cultural life) in some works (e.g., Det nya riket), particularly during the early 1880s. Strindberg's antisemitic pronouncements, just like his opinions of women, have been debated, and also seem to have varied considerably. Many of these attitudes, passions and behaviours may have been developed for literary reasons and ended as soon as he had exploited them in books.  In satirizing Swedish society - in particular the upper classes, the cultural and political establishment, and his many personal and professional foes - he could be very confrontational, with scarcely concealed caricatures of political opponents. This could take the form of brutal character disparagement or mockery, and while the presentation was generally skilful, it was not necessarily subtle.  His daughter Karin Strindberg married a Russian Bolshevik of partially Swedish ancestry, Vladimir Smirnov ("Paulsson"). Because of his political views, Strindberg was promoted strongly in socialist countries in Central and Eastern Europe, as well as in the Soviet Union and Cuba. CANNOTANSWER
