I won't go into details. It's not worth bitching about because ultimately, those people are never going to change. But I would ask everyone out there to please, please, please, try and live your life by the Dalai Lama's 3 R's:
1. Respect your self.
2. Respect others.
3. Responsibility for your actions.
What you say matters. What you do matters. Be accountable for your words and deeds because you are not an island.
Even when you want to be.
