Do you seriously believe, mathematician Shooby, that y=6*x is

Therefore y=6*x is "logically equivalent" to y=3*w, because x can be
rescaled by a suitable factor. It also logically follows that you are
willfully blind.

Think about what you are saying. For which combinations of [x,y] does one
equation equal the other? Only [0,0]! For [6,1] the first equation is
true but the second not. Therefore they are *not* logically equivalent.

I have said in advance that w=2x. http://www.everythingimportant.org/relativity/special.pdf
Where's the contradiction?
