You can't say something that goes against someone else is any way, be it minor or major, that won't make them react negatively. I've found out this much, and I know this thread will most likely receive negative feedback saying that when you do say something against someone else that they have the right to be angry. And it's ridiculously unfair, because, as I've said before, people just stay quiet when they should feel empowered enough to speak up.
