Like most people, I enjoy going on Facebook and looking through the Facebook pages of things I enjoy or causes I support, but I very rarely enter the comments section. I was reminded of why this was when I decided to read the comments on a post I found interesting. At least half of the commenters were commenting solely because they wanted to insult the topic at hand, and sadly, that is how a good majority of comments are on any big page.
Most of the pages have the subject being discussed in the title, and I do not understand why people who dislike it are on that page to begin with. I have a lot of things that I dislike or disagree with, and I have better, more enjoyable uses for my time than going through and commenting on posts about a subject I dislike. I can't imagine how boring someone's life must be to do that all the time.
I mean, even if it is an important issue that needs to be discussed, I promise, no one ever has had their opinion changed by reading a Facebook comment on a post. Your comment is most likely not phrased as politely as it would be in person because comments disagreeing with a subject are rarely written in a polite and constructive manner. Discuss the important issues in person and a lot of the hostility, anger, and misunderstandings will go away.
