The question "bashes" Mormonism in the way it is asked.
Someone asking an honest question does not go to pretty much the first question to ask Mormons in the anti-mormon playbook and ask "Don't Mormons believe that Jesus and Satan were brothers". Especially a week after saying that he wasn't going to get into beliefs of other religions.
A more correct an honest question about that subject might be something like "What do Mormons (or enter your church here) believe about the relationship between Jesus and Satan."
One religion might answer the the effect of Satan and Jesus being opposites, good vs evil, and talk about the duality in all things.
Another might say something to the effect of Satan is a fallen angel and go through how Satan wants to turn people away from Christ in vengeance against God.
LDS will probably go into their belief's in God's Plan and how Jesus and Satan work in to that. Further questions along that line, and depending on the member you ask, would reveal that the LDS belief is that we are ALL God's children (this is found in the Bible) and all brothers and sisters. You, me, everyone. By that reasoning Satan and Jesus would also be brothers, but NOT in body which is what the question "Don't Mormons believe Satan and Jesus are brothers" eludes to.
***Especially a week after saying that he wasn’t going to get into beliefs of other religions.***
What!!! Politicians lie. Say it ain’t so.
***we are ALL God’s children.... By that reasoning Satan and Jesus would also be brothers....***
Reasoning which is rejected largely by the knowledgable Christian. The Lord Jesus is Satan’s creator, not brother. We become a brother to the Lord through adoption. And, since I know that Mormons don’t believe that Satan is a brother through Christian adoption, this idea that Satan and Jesus are siblings is rejected by Evangelicals as a cult’s blasphemy. Hence, its use to sway votes in the Evangelical Republican community.
What a bunch of hooey.
When listening to someone who claims to be serious about their faith it is very telling if they are prepared to answer, or not. The whole bit about "it's not right to ask someone about their faith", or "they didn't ask the question correctly" is a way of avoiding the question. Avoidance is usually an indication that there is something to hide.
