Why no one is entitled to an opinion

The reason why people claim they aren’t entitled to an opinion is because of the fact that they don’t have to listen to another persons opinion and they also don’t have to agree to it I think this is fair because if you had to agree to someone else’s opinion that you didn’t believe was true it would honestly get annoying. So I’m not mad at all about this and I think that it is something that everyone should be fine about.
