When you disallow any debate, demand the use of made up words like cis and xe, and call anyone who disagrees a bigot there will be push back.
Xe? I know what cis is, now, what the heck is xe?
Cis and trans refers to the different position (same side or across) molecular components in molecules with the same chemical composition.
Xe is for Xenon an inert gas.
The other definitions are not based in reality.
