Start by not believing everything you hear and seek the truth.
Research what they say with an open mind

Hidden agendas of organizations that we THINK are for a worthy cause.

Hi, Rajmudaliar!

N0help4u makes some excellent points in her answer! However, I'm wondering if you're asking about around where you live, or the world in general? It would be helpful to know the specifics about what you're asking.

Thanks!
