ok so if we have someone like helen keller, she isnt worthy of moral consideration because she cant understand language?

she could still communicate for example By age 7, Keller had developed nearly 60 hand gestures to communicate with her parents and ask for things. ... Sullivan also taught Keller how to read braille and raised type, and to print block letters. By age 9, Keller began to learn to speak and read lips, skills she continued to develop throughout her lifetime.

ok, pigs can understand language as well they respond to voice commands quite a few animals are capable of this, as well as share their own languages

ok so a dog can do the same and they are still eaten same with horses while not eaten any more due to food they were eaten at one point in time

so? animals have language there for they are covered by your moral consideration
