A debate with Tomáš Koblížek on hate speech, with musical accompaniment by Jiří Trtík
Hateful expressions directed at various groups of people — Ukrainians, Jews, migrants, LGBT+ people — have become a widely discussed issue today, especially with the rise of social media.
Is it possible to limit hate speech while preserving the ideal of freedom of speech? Should we insist on freedom of speech if it serves as a shield for hateful expression?
Using concrete examples, we will explain what is considered hate speech in philosophy. We will also look at different approaches to defending freedom of speech as one of the key values, while at the same time legitimately criticising and limiting hate speech.
The debate will be interwoven with piano compositions by composer Jiří Trtík.
