Your deep feelings about a controversial issue might make it a very important topic of conversation for you, but not everyone you're with today is going to be open to talking to you about it. Resist the urge to preach or try to convince them to join you in your opinions. Not only could it potentially alienate people who really like you, it could do your cause more harm than good. Separate your passion and personal beliefs from social conversation today. Avoid topics that make people uncomfortable.
