  The framing of events in various media and discourse spaces is crucial in the
era of misinformation and polarization. Many studies, however, are limited to
specific media or networks, disregarding the importance of cross-platform
diffusion. This study overcomes that limitation by conducting a multi-platform
framing analysis on Twitter, YouTube, and traditional media analyzing the 2019
Koran burning in Kristiansand, Norway. It examines media and policy frames and
uncovers network connections through shared URLs. The findings show that online
news emphasizes the incident's legality, while social media focuses on its
morality, with harsh hate speech prevalent in YouTube comments. Additionally,
YouTube is identified as the most self-contained community, whereas Twitter is
the most open to external inputs.
