Hi Jim, long time no see.

A great enrager of Srians are mild questions about the energy (kinetic)
which vanishes
or miraculously appears depending on which "frame" they chose to place the
particle(s) in.

The same is true in Newtonian physics, the kinetic
energy of an object is zero in its rest frame
and the value diffes from frame to frame regardless
of what theory you use.

...........mostly in the form of the pathetic wail "You just don't
UNDERSTAND SR!!!!!!!!!!

Well that is certainly indisputable.

Especially bring it into arguement regarding "velocities don't add"; I
love it when they totally disregard conservation of energy.

A fine example, energy is of course conserved in SR.
