Real communication x online communication

I think that online communication is interesting,because you know a lot of people and you can discuss about a lot of things,but is much more dangerous than the real communication,which you know the person.In my opinion,the real communication is better because is safer knowing the person than don't know which whom you're chatting.However,milions of people chat with people who don't know. Because of this,happens a lot of kidnappings,sexual harassment and sometimes the person who kidnaps,can be a murder too,so we have to take careful with who we are chatting on the internet
