Why should we be nice ? Well from personal experience I can tell you that being nice you might get some people off the fence that were leaning towards the anti's side, i was on that fence once ( almost became an anti after losing a friend to a bullet to the head ) . But someone calmly explained to me that the gun did not jump into anyone's hand . I also can add that I have had a few great conversations with people about firearms and was able to give them some polite education . So a smile and calm talk can be a good thing. True there will be many who will not listen no matter how nice you are but there will some who will. And when you can educate one he can educate others as well.
