I didn't say you couldn't have an opinion. Just if you're going to have a stupid opinion, then you deserve to be called out for it. Not treat yourself like a victim after the fact.
Now, the other side of this coin is that when you're going to make a debatable or controversial opinion or an opinion that is not wholly supported by the vast majority of people.......and others disagree with you, don't get legitimately offended by it. You can defend your position all you want, and you can tell other people, "no you're wrong, and I'm right", but the fact is, if it is not a signed, sealed and approved opinion of the mass public, then people are justified in being able to disagree with you.
