Look Durden, a lot of us are quite aware of the presence of Satan in the world and the fact that there are Satanists around. We pray against it, maybe join the Angelic Warfare Confraternity, use the St. Benedict Medal etc.
Fr. Ripperger is a bit controversial, but there are plenty of other priests, some endorsed by the Vatican, who also caution us to be aware of demonic influences. However, we also believe that if we are firm in our faith in God and our love of Jesus and Mary, and also avoid certain activities such as drugs, witchcraft, and Ouija boards that can open doors and let bad creatures in, we do not have to go around fearing demons all day long.
You are presenting these concepts like they are something new, like we have never before thought about evil, Satanism, devils, or exorcists. Why are you doing this? Have you been personally troubled by Satan or demons and you feel it necessary to spread the warning to others? You are preaching to the choir but you sound so alarmist it is hard to take you seriously.
