What company buys what media has nothing to do with anything halfwit. Besides that I have given you videos from various sources.
This is scientific information that has been researched world wide. Rejecting the information because you believe that some parent company has some connection to something is an ultimate example of idiotic logical fallacy. I was expecting that from you that as like I said, you are scientifically illiterate imbecile who also does not have understanding of basic logical fallacies.
I posted these videos to make morons like you understand how the masks work as it is explained there in the way so 6 years old can understand.

I don't believe in anything you halfwit. I have no ideology nor religion. I only consider and revolved around possibilities according to what science has discovered so far. They constantly update and reshape what I know when new scientific information is updated.

Good luck travelling in Catalunya.
A lot of people are intelligent in Barcelona so they will consider you to be a complete dimwit.
Maybe except cholos/canis ("reggaeton chavs") and those delusional, ignorant, pseudo-anarchist dreadlocked yoga hippies that are many around here. They look like a clone copy of you so you won't have a problem with finding them.

Oh yes and pleaaaase mute me 🙏
You will do me a favour. I am afraid I am start losing braincells having a conversation with a moron.
