I understand honesty. I understand dishonesty. I get the point. I don't understand hostility. What does it achieve? Whom does it benefit?

I don't really get it either. That is why when I ask a question on here, I am responsive and friendly to everyone who answers. I never assume that some one has some ulterior motive for what they say or that if their answer doesn't fit my expectations, that they are trying to insult or attack me. If I asked questions and was immediately hostile toward some answers, that would make being on here much less enjoyable. I haven't run into anyone on here that I couldn't find something to like about, so to only be nice to some of them could mean that I miss out on some amazing interactions.
