People are allowed to post whatever they want to as long as it follows the guidelines and doesnt hurt anyone's sentiments. It should be completely okay to criticize ideas you disagree with ..It matters what you believe because your beliefs inform words and actions .

There is a difference between questioning and having a healthy discussion .. but what is wrong is when people straight away going to someone's face , not talking on FACTS and screaming 'your beliefs are trash' or come up with abuses.

Stupidity is limitless unfortunately . Saw people posting offensive and disgusting things maybe they get a feeling of satisfaction by doing so . This tweet won't stop people from doing so but atleast can make my mind more peaceful by letting my thoughts out.
