That's putting your head in the sand. You take every bit of criticism in multiple ways. One is in moderation because most people don't say anything if something's good. How often do you call anybody you interact with and say the service was really good today? Rarely. People usually call to complain, so you have to weigh that on the scales of justice in terms of criticism. Secondly, and most significantly, a lot of the criticism comes from someone who's rooting for his own team. If you say the truth, something that may be true about their team, they get upset. Often times in social media, the folks who will have the angriest comments will be from the team that loses. They've got no other place to lash out, so they'll lash out at the announcers.
