Having religion as part of the school curriculum in the US (United States) would not work in the same way it does in the UK (United Kingdom). I took RE (Religious Education) at both the Scottish Standard Grade and Scottish Higher Level educational qualifications. The US equivalent is WR (World Religions). WR, as an educational course, is typically seen at college / university level. People enrolled at said educational level can usually “choose” to take this course if they so wish. The reason I used the word “usually” in the previous sentence is that some colleges / universities may not offer said course. I digress. Would students attending high school and lower levels of education be able to “choose” to not take said course?
What difference would having religion based course on school curriculums? We might see an increase homophobia. Some schools, specifically in the South and other predominantly right-wing states, may choose to orientate their religious based courses to only teach from one set of religious beliefs. I guess there would not be anything wrong with this if the all the students taking that particular course were of the religion being covered in said course. Problems arise when students from different religious backgrounds are in the same classroom. Which religion is covered? The UK does not have a problem here because as many religions as possible are covered in the aforementioned RE course. This is unlikely to happen here.
Would you impose one set of religious beliefs on all? I am sure there are parents out there that would not want see religion beliefs they personally do not subscribe to as being part of their children’s education. Is it not just as unacceptable to impose Judaic beliefs on Muslim children as it is to impose said same beliefs on Christian children? The same can be said of any set of religious beliefs. Is it not possible to see that, even thou the US population is predominantly Christian, the said population is made up of numerous religious backgrounds? When it comes to religion, there is no one size fits all.
