In the contemporary global landscape, the advent of information and communication technology has interconnected societies, fostering increased civic engagement. Notably, social media platforms, a manifestation of this technological innovation, play a vital role in political discourse, drawing active participation from politicians, political parties, and their supporters. However, the utilization of these platforms in the context of electoral campaigns, particularly in nations like Nigeria, has raised concerns due to the dissemination of political information carrying adverse repercussions. This study delves into the examination of the public's perceptions regarding hate speech on Facebook during Nigeria's 2023 general elections. Employing a survey research strategy and leveraging convenient sampling, data were collected from residents within the geographical scope of Kwali Area Council, Abuja, Nigeria. The research framework drew upon the public sphere theory to elucidate its core objectives. Findings underscored the prevalence of hate speech on Facebook during the 2023 elections, attributing it to factors such as financial inducements, conspiracies, lack of citizen journalist training, religious interests, and sectional, tribal, and political influences. Notably, Facebook emerged as a platform for disseminating speeches that fueled animosity toward politicians, tribes, religions, and sections, instigating widespread antipathy without substantial knowledge of the targeted individuals or candidates. The research also highlighted the use of Facebook for insults, harassment, and the propagation of divisive narratives, contributing to tribal and religious conflicts, heightened tensions, attacks, disparities, and internal discord. This study's implications suggest a potential undermining of Nigeria's democratic progress. As a remedy, the study advocates for the responsible and positive use of social media platforms by users, especially during critical events such as elections.
