May not be maths, but is very logical.

Human beings can understand logic, have knowledge of past events and can imagine outcomes of their actions, based on such knowledge and personal experience. Why then do people hold extreme opinions and refuse to change them when presented with facts to the contrary? Discourse on social media has become more polarised, and hostile to those with other views. This can apparently be explained by using Bayes' Theorem which shows how the same set of probabilities maybe be used to arrive at completely opposite conclusions. Since the vast majority of us know only basic maths do people use maths instinctively or are human beings stubborn because emotions make them illogical. People use many methods to arrive at conclusions which may seem unreasonable to others but is not without logic. We see women being treated as sex slaves by ISIS in Syria and Iraq. Huge numbers of sexually repressed young men are joining ISIS for sex and to have control over women. ISIS pamphlets justify rape of women and girls, saying that it is permissible to rape kufr women and children who will not convert because rape is a form of conversion. When you read harrowing stories of such women it is easy to believe in ' Love Jihad ' in India regardless of how much liberals rant against it. Tolerance of people with different beliefs creates harmony, encourages cooperation and is healthy for society but if it is seen to be enforced then opinions become entrenched. Thus strident secularism is seen as hostile to religious belief and results in fundamentalism. Politicians and civil servants love secrecy, which gives them power over the masses. There is widespread belief that Netaji Subhash Chandra Bose did not die in an air crash in 1945. Even if he did not he must have died of old age by now. Still the government refuses to release old files regarding his death because it may harm ties with other nations. Even if agents of some other nation murdered Netaji all the people involved are likely to have died so it is very unlikely to have any impact on international relations today. Absence of honesty leads to suspicion and anger so some members of Netaji's family believe that the Congress is behind the lies about is death. Similarly, the post mortem report on former Prime Minister, Lal Bahadur Shastri has been kept secret. Surely his sons have every right to know how their father died? It is not surprising for people to become infuriated and form their own opinions. A common tactic, adopted by pompous egoists, is to deride others as fools with conspiracy theories, which is insulting and only serves to entrench opinions. Was Nehru's grandfather a Muslim? Did Feroze Khan become a Gandhi to marry Nehru's daughter, Indira? If so, secularists should be proud of that. Why do they hide it? Maths cannot work with secrets.
