An effective rebuttal to the counterclaim could be:
"While cyberbullying is indeed a serious issue on social media, it's important to recognize that social media platforms also provide tools and resources for individuals to report abuse, connect with supportive communities, and raise awareness about such issues. Moreover, the ability to bring to light marginalized voices and create spaces for advocacy has led to significant social movements that address and combat bullying and discrimination, fostering a more informed and compassionate society."
This rebuttal acknowledges the concern of cyberbullying while highlighting the positive aspects and potential solutions that social media has facilitated.
