It's been my experience that people believe what they want to believe, unless some great need arises and they have no answer. No one wants to be educated or enlightened, they want to be comfortable where they're at. Unless like I said they are in a crisis and have no answers, then they will try to listen, or might listen.
Sorry you had a bad day. I hope tomorrow is better for you.
What they believe doesn't matter much anyway. Doesn't matter at all, in fact. What they believe doesn't change who you are unless you give them that kind of power. I wouldn't. We can't control anybody, just our own inner world and our life.
