Assumptions are not a problem if we check them out. It's the second, usually subconscious, ones that can lead to problems. When one makes assumptions that aren't based on fact, we have opinions. Problems begin when one assumes their opinions are facts.
A number of assumptions were presented as facts in the Jan. 20 letter, "Revisit Roe with the unborn alive, kicking." An 18th century quote was used to define a person. It included "one like us who had been formed by God in the womb." Because the existence of God hasn't been proven scientifically and definitively, this was an opinion, not a fact. A second assumption made was that the first assumption, the existence of God, was a fact when it was merely an opinion. Because this was an opinion, everything connected to the ideas presented were opinions, even though they were presented as facts. One wonders why there seemed to be such an intense need to assume these opinions as facts.
This problem was also apparent in another letter on the same date, headlined, "Let's be better than Trump-bashing." As I've written, I don't hate President Donald Trump. What I and others hate is what Trump's doing to the country. Hate is assumed to be fact because it supports the conclusions already arrived at, none of which are provable. (It’s kind of like saying someone hates Hillary Clinton.) The letter bemoaned "politicians, media, and secularists who ram agendas unreconciled with Christianity down Americans’ throats." Ironically, but not coincidentally, the same could be said of religious extremists who want to change the government and control the everyday choices different people have in life. The government was purposely created so there's a separation between religion and state.
Religious extremists seem to want to control society, based on their primary assumption there's a God and their secondary assumption that their original assumption is a fact.
