I have specifically and repeatedly declared them as humans. You are the one who declares them sub-humans. Please stop eating lead paint chips.
“I have specifically and repeatedly declared them as humans.”
Per your definition someone that does not have the same rights as humans is subhuman.
“You deemed biker gangs sub humans, which by definition do not have the same rights as humans.”
Ergo, if you have less rights than other you are sub-human.
