If you post something on social media, you are explicitly inviting people to comment and share their opinions. If that is not your intent then set privacy settings accordingly.
Regardless if you post something and are offended by respectful differences of opinion, and go so far as to silence those opinions, then **you** are the problem.
If you expect people to listen to your views on blast without giving them the common decency to reply, and be listened to in return, its time for you to reevaluate yourself because you are likely the perfect example of why the world is falling apart right now.
