| PMB is sometimes crabby and sometimes takes extreme positions.  However,

Yes there is. The unsupported assertion is his light clock. Any real light
clock gets dragged along with the Earth, but the speed of light within it is
source dependent.
All relativity makes the unsupported assumption that the SoL is observer
dependent, and that applies to Brown's page too. Therefore Brown is a crank.
Actually, he's worse than that. I've told him what is wrong with his light
clock and he hasn't withdrawn it. Therefore he is a bold-faced liar,
spreading malicious gossip to unsuspecting students of science. I've told
you, too, so that tars you with the same brush. You too are a bold faced
liar.
