It's that people are looking for a fight (or just to insult) that I usually try not to say anything at all. But, sometimes, I get this overwhelming need to say something. Thing is, though, I don't think it's so much about getting into anything with the person but simply to supply a differing view or to correct a common misconception. Even if the person responds with more snide comments, at least I provided some food for thought for those willing to actually think.
