I think you're wrong; and the logical conclusion of your position is nihilism.
And do you really think you're the ONLY person making this argument? It's all over my TV and the editorial pages of outlets like The Guardian.
Arguing that "America is too awful for our pure politics" is a way to let shit tier conservatives off the hook for blowing a winnable election to a reality TV show nazi, so of course they're broadcasting that message.
That's probably where you got the idea.
