Not a burn at all. A lazy, defensive comment at best by a person who should be listening to the context of why people are upset and try to have a constructive dialogue. It's like moving into a neighborhood and waving your willy out on the sidewalk and then saying, "we all have private parts! Don't get offended! If your children don't like it, tell them not to look." 

If you don't like to hear about the reality and experience of people that could be your friends and customers then maybe you should take your willy and live on a nudist colony. It's about CONTEXT.
