Social media sites are made up of many pros and cons.
Some pros of social media are that it allows people to be more social with others, maybe to open up more than they are in person.
Social media sites allow people to make new friends, express who they are, and pretty much be themselves.
Cons can consist of several things, one main problem of it, cyberbullying. Social media sites have led to the suicides of many people across the country and over seas. These sites may cause people to crawl into a shell and hide out due to harsh insults and comments.
The thing is, people don't have to make accounts on social media sites. Most people are aware of the different possible things that may happen to them. I'd say social media sites shouldn't be allowed, but I personally think that they are an overall positive influence. ( In a sense.. ) Even if someone is being cyberbullied, they are able to block these people from accessing their profile, and if harassment continues the victim can either notify authorities or the school they attend ( if in school ). I'm sure the matter would be handled quickly as bullying is being viewed more and more as suicides have become a big problem.
These social media sites do not force people to sign up, people do it at their own will.
The sites give them the oppurtunity to escape the bullying by blocking the attacker or reporting them.
So in general, yes I think social media sites are good for our society.
