So like humans have done forever, we search until we find something that agrees with our opinion. With that you have one group saying that it is important to wear a mask and another group saying... Hell, it doesn't matter. If you don't want to wear the mask take a wild guess on which opinion you are going to go with.
When there are two conflicting official opinions, stated by people that should know the one thing you can be sure of is that one of them is wrong. You will decide what is right based on which one you want it to be. So in the case of the mask. Your agreed opinion says.. nope not worth the material they are made with, the other side says... No they are not 100% effective, but they do block a whole lot of virus germs from getting to others or to yourself. That would be my agreed opinion.
So if your right then I wasted a few months wearing something that I really didn't want to wear, but I did it for myself because I feel the more people that wear them the better chance I had. If I am right, you may have exposed yourself to a deadly virus that has been killing people DEAD for the last few months. I find that my way is better because at the end of this I have a better chance of being alive than your insistence that they don't work. The choice is yours.
In that same line the choice of insisting masks be used in places like Disney is not just for the protection of guests, but also the protection of the company, it's reputation and it's future. Remember that they are taking a massive income hit because of this. That tells me that they didn't make this decision without a lot of discussion. You don't want to wear them you don't go. That's my choice. You cannot decide that what you want supersedes that possible risk on others that you are creating. That freedom that is bantered about so easily, comes with a required responsibility. You cannot have one without the other.
