Dislike Button on Facebook: Boon or Bane

I saw in today's newspaper that Facebook is going to introduce \"Dislike\" button. They should not do this because this will create more problems in society. In real life, whenever we see someone or something that we don't like, we don't speak ill about it on face. But when we are browsing on social media platforms, often we care little about the real life consequences. If dislike button comes, it's inevitable that people will feel hurt when someone puts a dislike on his/her photos, posts, or other activities. So, this should not happen. We already have so much problems in real life. Please Mr. Mark Zuckerberg, don't make Facebook a problematic platform too.
