No, you are not entitled to your opinion
OK, so this really isn't a debate, but I don't care. So often we are confronted with "It's my opinion so you can't say I'm wrong" or other crazy values that I think this well thought retort to the whole "I'm entitled to my opinion" is worth a read to all who care.
If tl;dr, here's he argument breifly:
... I say something like this: “I’m sure you’ve heard the expression ‘everyone is entitled to their opinion.’ Perhaps you’ve even said it yourself, maybe to head off an argument or bring one to a close. Well, as soon as you walk into this room, it’s no longer true. You are not entitled to your opinion. You are only entitled to what you can argue for.”
It's amazing to me that, unlike in the real world, people on the internet will wear "everyone thinks I'm a moron" as a badge of honour.
