I get it! It is only true if it i in agreement with you and your doubtful claims.Yeah, I've already provided a link about the mask boxes which you have chosen to ignore. There have also been various studies about how masks work that have been posted across the board as well.

That right wing echo chamber has most likely permanently fucked with your heads where you have trained yourself to follow a very narrow path and any deviation be it new facts or information short circuits your brain and you have to run back to the path. Whether it was Limbaugh or Hannity or Carlson or Trump, you must always please your daddy.
