This study investigates how online social networks affect political tolerance in post-coup Egypt. Analyzing real-time tweet data across elite and non-elite networks, we find an unexpected relationship: greater ideological diversity on Twitter is associated with lower levels of political intolerance. This correlation persists even after longer exposure to diverse feeds over time.

Our research delves into the mechanisms behind this finding, suggesting that social norms within these online networks shape users' willingness to publicly express intolerant views. Bullet points highlight our key insights:

• Counterintuitive link between network diversity and reduced political intolerance
• Consistent relationship across elite vs non-elite Egyptian Twitter networks
• Persistence of effect over longer engagement periods

This study significantly contributes to the literature on political tolerance by offering fresh perspectives from an authoritarian context where polarization is pronounced. It provides crucial nuance to ongoing debates about online echo chambers, showing that diverse exposure may foster greater openness in politically polarized environments.
