When presented with evidence about an old Earth and the evolution of species, a common retort among many young-Earth creationists is the typical "you weren't there, you didn't see it; you don't have a time machine so you can go and look at what really happened." They often also argue about how their claims is based on actual observable facts and not just "guessing what happened a long time ago."
However, when the argument from the distance between stars and galaxies comes up, suddenly their position changes completely. Suddenly it's all about "maybe the speed of light has changed, maybe this, maybe that." Suddenly there is no strict adherence to observable facts, and it's all just guesswork. Tons of maybe's and perhaps'.
Like with everything, whenever a certain principle is favorable to their cause, they are all for it, but whenever applying that exact same principle would be unfavorable to their position, it's suddenly nowhere to be seen and never mentioned.
Talk about hypocrisy.
