You have an opinion about everything. I know you do. I've seen you sharing it on Twitter, and I'm sure you're sharing it on Facebook too. After all that's why you have a Facebook account, right? I'm kidding. No I'm not.
Here is the deal with opinions, specifically how you should share yours and how you should receive others.
If you are sharing an opinion, be sure to back it up. What do I mean by that? I mean be sure to tell me why you think what you think. If you can't do that, then your opinion holds no weight. It doesn't mean that your opinion is wrong, it just means that you're not smart enough to know why you think that way.
If you are on the receiving end of an opinion (read: if you have a social network account), and you hear an opinion that offends you, consider the paragraph above. If the person can't back up their opinion with their own thoughts then feel free to not be offended. A person who can't justify why they think the way they do doesn't deserve your time or concern.
