Not talking so much about the internet as most people self-select sites with people who (mostly) agree with them. I am talking about REAL life.Bees don't waste their time trying to convince flies that honey is better than shit.
More seriously, I only have one life to live. It doesn't seem logical to trade time in my limited life arguing with strangers on the internet at the opportunity cost of spending time with my children or otherwise pursuing happiness. That's not to say I've never done it, I just hope to do less of it, and maybe even none some day.
