Aside from the fact that your thesis is without any evidence, much less primary evidence, it is rife with logical fallacies - assuming a false "if not x, then y" scenario, leaves out about 30 other people that the "hidden haters" could be shilling for but yet singling out Rubio, has absolutely zero basis from any posts I have every seen here, and is essentially.....well....stupid.
Other than that - yeah, it's a good hypothesis.
"In the beginning of a change the patriot is a scarce man, and brave, and hated and scorned. When his cause succeeds, the timid join him, for then it costs nothing to be a patriot."--Mark Twain
