I couldn't agree more with you. Had the Gamma Phi Beta sorority hung a sign that read "We support the Russian-speaking people of Crimea in their struggle against Ukraine," the result would have likely been exactly the same. We are spoon-fed what we should believe by our news media and any other opinions are immediately squashed.
On the flip-side, imagine the uproar had the sign read "SINGLE-PAYER HEALTHCARE NOW!," "WE ARE THE 99%," or "WORKERS OF THE WORLD, UNITE!" and the sign removed by order of President Kelley, you can bet the farm that civil rights and free speech attorneys all across the country would be booking flights to Grand Forks immediately.
