The word “hero” is losing its meaning.
That's true. Calling every person who ever donned a military uniform a "hero" really demeans those who did truly heroic acts while wearing that uniform.
Does getting shot down and captured by the enemy automatically qualify anyone for "hero" status?
Bo Bergdahl was captured by the enemy. And FWIW, John McCain has done more to destroy the Constitution and American Sovereignty than Bo Bergdahl.
Right! Look up the meaning of hero on Wikipedia. McCain was just one of the thousands of POW and he did nothing special.
