Ideological extremism negatively impacts political discourse by polarizing opinions and reducing opportunities for meaningful debate. When individuals or groups adopt extreme positions, they often dismiss moderate views, leading to an us vs. them mentality. This polarization can manifest in vitriolic rhetoric, inhibiting constructive dialogue and compromise. Additionally, extreme ideology may influence policy decisions that cater to narrow interests rather than public welfare. Ultimately, a lack of civility stifles cooperation among political factions, undermining the overall democratic process and fostering division within society.
