It is a natural tendency in common men to love their country, state, district, city/town and the street where they live. Same thing happens in the case of their religion.
They love their religion because they were born into the religion that belongs to them. If a Hindu who loves his religion had born in Muslim family instead of a Hindu family, he would have loved Islam, and not Hinduism.
Hate is a companion of love. So most of the people who love their own religion, like to hate other religions.
Staunch believers think that their religion is the oldest one and superior to all other religions. They also think that their religion is the most scientific. They don’t know ABC of science, but think that today’s science already existed at the time of their Prophets and Avatars.
In India, the Vedic fanatics always like to tell that there were airplanes, radio, computers, internet and many other machineries & technologies in the Vedic era. They say that the Europeans discovered these things by reading the stolen ancient books of Vedics from India. I am afraid, why then the Vedics themselves not discovered these things in spite of having these books with them for last many centuries?
Such type of people belonging to any religion cannot differentiate between science and technology. For them both the things are one and the same. In fact, fundamental science is an area of genius people and technology is applied science, which does not require much intelligence when compared to prior one.
No doubt ancient Indians, whether Jains or Vedics have done a lot of work in the fields of cosmology, medicine, biology, advanced mathematics and psychology. But these subjects go from over the heads of common believers of Jainism and Vedic religion. So while speaking about their religion being scientific, the Vedics talk about airplanes and Jains talk about health science behind not eating at night.
Modern science has proved many concepts in the religions as just a stupidity; but the staunch believers of religion like to take support of science to ‘prove’ some of the concepts in their religion. On other places, they like to criticize the science. They believe that the science is destructor of mankind, but the fact is that religions are the biggest enemies of humanity. Remember Crusades and Jihads, Hitler and Laden. Although all terrorisms are not based on religion, the religious terrorism is more dangerous when compared.
Science does not belong to any specific ethnic group. It does not teach to hate people. It does not claim that it knows the ultimate truth, but it is always nearer the truth than the so-called truth told by religions. Religions have helped to spread blind beliefs, while science always destroyed them.
Believers of religions take advantage of all the technologies based on science. They use television, computers, internet, mobile phones etc. for promoting their religions, but at the same time they criticize science. So the believers are the most ungrateful people in the world.
Science has already overtaken all the religions, and the religions have to change according to science. You might have read that the Pope had to apologize for opposing and punishing scientists by clergies of the past, and also for opposing Darwin’s theory of evolution.
If a religion does not change it will be automatically become an out of dated faith.
