Well I'll answer part of that... if it really needs explaining
Why do you wash anything (dishes after rinsing) even though you know (or should) that chances of actually getting sick any time soon are fairly remote unless your immune system is shot? You do it 'because'. Because you prefer things to be clean. NOT supersterile, but life is more pleasant when things are clean. And when you breathe into/onto something all night that's up against your face, it's civilized and more pleasant to have it clean next time you use it. And if perchance some microbe actually did manage to affix itself after floating around the room, being on your beard, your long hair for the day, well it will hopefully go away in the wash. IF however, you tend to harbor Ebola and pestilence in your bedroom, I suppose sterilization would be called for - you never know after all. If you really need it explained... I mean waving a kid's lollipop around in the air for 10 mins (let alone being dropped on the floor) is standard and most kids survive.
Are you having fun yet?
I'm confused, Julie, I thought Palerider was THE source for valuable information on this site and yet you tried to answer for him? Why hasn't he provided evidence as to what constitutes a reliable study and that the Taiwan study wasn't peer studied? Is he really THE source, or is he just smart enough to bluff others here?
So to recap what you said: 1) Only people with compromised immune systems get sick; 2) People clean due to a penchant for wanting things tidy, as doing so civilized; and 3) A sterilization is needed in the event of Ebola and pestilence, such as the bubonic plague. Really? So they only way a person can get sick is if the humidifier contains days old water tainted by Ebola and only when the wearer has an already compromised immune system. Even at that point, the only reason the wearer would want to empty and clean their CPAPs humidifier tank is due to a desire for civilized and tidy surroundings.
How about if we just have the infamous Palerider respond? He's had what, 8 hours to do so ad he's yet done so. I'm beginning to question whether he really is such a valued source of knowledge. The floors yours, once again, Palerider.
Dear Chevie: The oft echoed teapartier talking point that liberals/progressives are mean is due to intelligence, or more specifically lack thereof. Liberals/progressives grow tired of hearing Fox isn't News viewers parrot untruths while being impervious to facts, so we begin to ridicule the knuckle draggers in society for lacking even the minimal knowledge needed to be politically engaged. AKA the Dunning-Kruger effect and aka right-wing authoritarians (Professor Bob Altemeyer). Not to worry thought, Chevie, if this is all over your head please don't worry, as studies have proven over and over conservatives are the least intelligent of all political ideologies, so you're right where you need to be.
