I'll stand up for what I think is right, depending on the situation. Like the day I finally stood up to my step-dad. No one was going to judge me negatively about it except him. In fact, when I did it, I inspired my family to fight, too. It was the one thing that led to my mom making the right decision of separating from him.
For my beliefs? I'm quiet about my Atheism. I don't like to get into arguments about religion because in the end, no one can win. I'm empiricist, too. Boy does that make some people pissy when I tell them. I tell them to just accept it and move on, or leave me alone. I don't take that kind of crap.
If I see something going on that I think is morally wrong, I usually won't express that UNLESS the person doing the wrong asks my opinion. You know, like abortion. I think it's wrong, yes, but I also think we should be allowed the choice. Everyone has their own feelings on the matter. I'm not about to poke a finger at their chest and call them evil, because it may be right to them. Who am I to tell them they're wrong? That's the same for anything else, really. Drugs, abstinence, vegetarianism...
Now, if it's something like animal abuse or child abuse, hah... Expect me to enter a rage and chastise the abusers. Before calling the cops, of course. Those bullies need to go to jail.
I'm also strong in my decision that the death penalty is necessary. I believe in the 'eye for an eye' statement. If you kill someone, then you should be killed as well. Getting cooped up in an asylum seems like torture. Spare these killers the inhumanity and just give the lethal injection. -__-; Actually, for an English class I took in college, we had a debate about this. The side supporting death penalty was already small numbers. After some debate, they got intimidated by the non-supporters and switched to their team. Myself and 2 other classmates were left standing, continuing to argue why our beliefs are what they are. I was disappointed to see other classmates give up so easily.
And if a person ever has a problem with me and my ideas of "right", I tell them, I ALWAYS tell them: Take me or leave me. Because I don't need non-accepting jerks in my life.
EDIT: Wow, I wrote a lot. .__.; *flees*
