People getting offended is not the issue. If everyone chose to never offend anybody else, my mother would never know that she makes bad pasta and we'd all have to eat bad pasta 3 times a week.
You want to draw the line at marginalizing a group of people or trivializing something serious like racism. But you want to make sure you are doing it in a way that isn't inhibiting legitimate thoughts, studies, projects, etc. from making it into the public sphere.
Every time you censor speech you stifle legitimate dialog because people will be uncertain whether their thoughts are legitimate or just offensive.
