Who has claimed that those merely stating that they won't vote for Romney are campaigning for Obama? Not me. Obviously one has to do more than this to be objectively described as campaigning for Obama.
(One example of what more an Obama supporter might do is to deliberately use tendentious, straw-man arguments against Romney supporters. Seen any of these lately?)
I say that numerous persistent and prolific FReepers are doing far more than simply stating that they won't vote for Romney, and that these posters are by any objective standard campaigning for Obama. Are you saying that I am wrong?
I won't if you can show me a significant number of examples of what you're saying.
