Great thoughts!
I think present day politics is the main cause which is dividing people on their thoughts and views. Politician are deliberately dividing people because they know that by converting individuals into a mob is much beneficial for them. It is not an easy thing to change individuals point of view one by one but it is an easier thing to divide them in groups and then use these groups against each other which finally serves the purpose of politicians (and their masters!)
Ordinary man is not aware of the fact that public is not choosing its leaders,in fact it is choosing its rulers! A leader is a totally different person who leads public while for a politician, politics is nothing but a profession. Politics is a way of earning for most of the so called leaders. These professionals do everything which is necessary for their survival in this business.
Why we forget that politics is not an easy thing. A person has to undergone a tremendous pain and suffering in the course of election. He has to bear a lot of pain, has to meet many persons, has to speak lie, has to invest his/her hard earned money, even his/her life is threatened in this pursuit. Is someone doing this just for ignorance public? I don't think so. Everyone do everything just for his/her own benefit.
If someone has invested a lot of amount, then why will he/she think about the common public? He/she will anything to secure his/her business. If in this course he/she will have to divide people, he/she would definitely do it.
Hence, in my view it is not a wise thing for us to be divided by politicians. We should accept them (cautiously) as far as their policies are not against the public interest. We should not fight or hate others who are not agree with us.
