Different words all meaning the same thing. There will always be an opportunity to speak up for your personal beliefs but I understand the fear of being the first one to speak up is always immense but just remember that one day you're going to have to look back & see that when the opportunity to stand up was there you didn't take it.

The first that I was never going to <inserts profanity> keep my mouth closed again whenever I saw something I had an issue with. It's extremely easy just to cower away when the going gets tough or play dumb as a box of rocks but the real courage comes with being able to stand up on your two feet knowing that you would rather be ostracized for your convictions then fit in.
