The whole basis of Einstein's special theory of relativity is that nobody is "stationary"; i.e. there is no experiment possible which can determine a "stationary" reference frame. So if you want to argue, do not use "the one who is stationary". If you want to do that, then join the "stationary flat-earth" society!
