I agree with this. While social media is a way to express your feelings freely, it should also be done with respect and should not be targeted to hurt people.
Social media can lead to nasty propaganda about the other political group. People from one side of the political group will say very bad things that may not be true.
Although social media brings people together, it will bring people with the same beliefs and could lead to some extreme beliefs.
Social media is not good for democracy because it can cause polarization. Many groups will not agree with the other side and join in with groups of the same ideas which leads to polarization.
