Do not be led by fear. Some concern is fine but to assume that all negative or fear-based ideas will come true is unnecessary.
People say a lot of things. Ignore most of them. Also, understand their bias. They are probably trying to influence you for a reason. If they use facts, they are genuine. If they name-call, use fear or invoke strong negative emotion, they are playing you for a fool; and enjoying your naivety.
