You are trying to reason with a person who takes "his" opinion from his teacher. In blind fate without looking at the world around him. He won't change his opinion whatever you say. Using statements that massively contradict each other as well (as i just pointed out towards him).Innegativeion said:You are going on the false assumption that chromosomes serve any purpose further than storing the information that amino acids use to make proteins. The chromosomes themselves are not used to make organs, proteins are. If the chromosomes' ability to make certain proteins in certain ways are blocked by hormones, then they might as well not be there at all(disregarding non-sexual characteristics on the X chromosomes, of course).
Rather then really explain (or rather probably just parroting his teacher) he feels the need to insult. I waste no time with people like that (and the ignore button is the best solution for that)
