Read the following excerpt from a rhetorical analysis of awareness campaigns on social issues:
"Despite the echo chambers of social media, real activism emerges from genuine empathy, not merely hashtags or fleeting trends. The urgency of our causes demands that we speak not just from our screens, but from our hearts. A true movement involves the tangible actions that resonate beyond a click, actions that infuse our narratives with spirit and purpose. To merely 'like' is insufficient; we must endeavor to engage in substantive dialogues that forge connections across diverse communities, fostering a deeper understanding of one another and the struggles we face together.”
