Is social media guilty of murdering free speech?

I have been seeing a couple of stories lately regarding people that have lost their jobs because of things they have posted on social media...

This has made me think whether this monster (social media) that we have created is not robbing us of some of the liberties we have fought for. Mind you I don't condone or agree with people who spew hate speech and tie it with a free speech ribbon and expect you to swallow regardless of how foul it is, but at the same time, we can't all have the same views and agree with each other all the time. Dialogue and disagreements are a crucial part of a free society, yet the clap back that people receive from expressing their opinion or simply posting their lives online is ridiculous. 

The group hardest hit by this are celebrities because whatever they post is a potential headline for tabloids and hard news lately. We seem to choose to forget that they are human like all of us and we revel in seeing them get into hot water because of something they have posted. We have become harsh judged and jurors in the social media court of public opinion while safely hiding behind our smartphones and laptops. We seem to think that this gives us the license to be rude, crude and nasty towards each other. We say and do things that we would never say if we met face to face. We misinterpret this as the power of free speech forgetting that with power comes responsibility.

I am someone who believes in being able to express my opinion but I do so in a responsible manner and believe that anyone who does the same deserves to be able to post what they want on their own social media page. If you don't like someone's opinion then stop following them or liking their page because there will always be racists and bigots in the world and that might be your only recourse.
