An anonymous reader writes "Martin Gräßlin, maintainer of the KWin window manager, writes an informative blog post about his experiences with the less favorable pockets of the Free Software community. Quoting: 'Years ago I had a clear political opinion. I was a civil-rights activist. I appreciated freedom and anything limiting freedom was a problem to me. Freedom of speech was one of the most important rights for me. I thought that democracy has to be able to survive radical or insulting opinions. In a democracy any opinion should have a right even if it's against democracy. I had been a member of the lawsuit against data preservation in Germany. I supported the German Pirate Party during the last election campaign because of a new censorship law. That I became a KDE developer is clearly linked to the fact that it is a free software community. But over the last years my opinion changed. Nowadays I think that not every opinion needs to be tolerated. I find it completely acceptable to censor certain comments and encourage others to censor, too. What was able to change my opinion in such a radical way? After all I still consider civil rights as extremely important. The answer is simple: Fanboys and trolls.'"
