you still does not do the basic: 1. acknowledge the other party's point by rephrasing 2. thank/praise the other party for their effort. what is common good? you think common good is a product. but most human beings think that making your teammates happy is a worthy common good. Without making your team happy, you will not get anywhere. Talking over other people, interrupting other people, making other people feel that their concerns are ignored by you. these behaviors will bite you very quickly. If even on internet you could not bring your self to Ack/Thank, then you 90% can't do it face-to-face. Most people will be unwilling to waste time on someone who refuse to ack/thank.
