The OP. If not, then what are you trying to say?
You referred to my argument "against masks helping prevent transmission of disease". I dont recall ever making any such argument.
If any of that were true, then you know your own argument against masks helping prevent transmission of disease is bullshit.
The opening post and thread title both reflect the title of an article titled "The Science is Conclusive: Masks and Respirators do NOT Prevent Transmission of Viruses." There is nothing about "helping prevent", in the title of that article, see the all caps word in the actual article title.
