I live in the United States, where it appears things must be very different. The suffering here is caused by certain Christians. Christianity is in the overwhelming majority here, and as a result, Christian beliefs, traditions and mores are ubiqutous, and unbelievers are punished.
As an example (you may not believe this is possible in a modern world, but it is true), a national leader could not be elected here if he or she were an unbeliever! Very ironic, isn’t it, as our nation was actually based on freedom of belief!
Until just 40 years or so ago, houses were sold with restrictive deed covenants that prohibited their sale to Jews. Great Universities had “Jewish Quotas” where the number of Jewish students was restricted, and many country clubs and resorts did not allow Jews to become members. Similarly, in the professions of law, advertising, banking and brokerage it was necessary for Jews to form Jewish firms, because Jews were not hireable at the majority institutions.
Now things are somewhat different, but in most ways it is still most comfortable to be a Christian here in this country. It is especially undesirable at this moment to believe in Islam, for example.
Also Christians continue to have outsized power in imposing their beliefs on others. A majority of Americans continues to believe in the right of a mother to decide, with the assistance of her doctor, whether or not an abortion is necessary, but Christians have imposed restrictions on this right, and continue to clamor for more.
Homosexuals are among the groups in this country most punished by Christians. They have been singled out as a subset of humanity whom Christians wish not to be able to express their love for one another, and they suffer a great deal as a result.
Where you live, it must be very different, so I am eager to hear from you how, in your land, Christians are an oppressed minority.
