It's a joke. DHMO = 2H, 1O = water 
   OOOOOOOO man ! :-}}} You've got me ...
I should have been paying more attention.
I am truely ashamed.
I must even admit having read some previous thread about 
some congressman (? or how do they call them) wanting to ban H2O. My first tought was: how can you possibly do such a thing without properly informing yourself.
I already tought the name "DHMO" to be a strange one. A bell was ringing very faintly when reading: 
PC2K - 
Read the words Dihydrogen Monoxide (DHMO) carefully and remeber those science classes... 
  
  and this should definitely have woken me up.
But while quickly reading the posts, I didn't watch wich post replied to wich.
