The strength of internet as a medium is due to the fact that now, especially with the rise of social media, anyone can voice his/her own opinion. And this opinion can be read or heard by anyone in this world.
Because of this internet, the "marketplace of ideas" is enlarged to one that is unparalleled throughout history. From this, opinions and ideas that despicable will be rejected by the masses, while those that are socially responsible will be accepted.
