I didn't read all 70 questions ahead of me....
Just ask them who mediator between man and God is. If they say Jesus, ask them to clairfy. Is Jesus your mediator? If they say yes, you can take them to WT articles that teach otherwise.

? Is Jesus the "mediator" only for anointed Christians?
The term "mediator" occurs just six times in the Christian Greek Scriptures and Scripturally is always used regarding a formal covenant.
Moses was the "mediator" of the Law covenant made between God and the nation of Israel. (Gal. 3:19, 20) Christ, though, is the "mediator of a new covenant" between Jehovah and spiritual Israel, the "Israel of God" that will serve as kings and priests in heaven with Jesus. (Heb. 8:6; 9:15; 12:24; Gal. 6:16) At a time when God was selecting those to be taken into that new covenant, the apostle Paul wrote that Christ was the "one mediator between God and men." (1 Tim. 2:5) Reasonably Paul was here using the word "mediator" in the same way he did the other five times, which occurred before the writing of 1 Timothy 2:5, referring to those then being taken into the new covenant for which Christ is "mediator." So in this strict Biblical sense Jesus is the "mediator" only for anointed Christians.

16 Just as the ancient nation of Israel was in a covenant relationship with Jehovah God through the mediator Moses, so the nation of spiritual Israel, "the Israel of God," has a covenant relationship through a mediator. (Galatians 6:16) It is as the apostle Paul wrote to his Christian fellow worker: "There is one God, and one mediator between God and men, a man, Christ Jesus." (1 Timothy 2:5) Was Moses the mediator between Jehovah God and mankind in general? No, he was the mediator between the God of Abraham, Isaac, and Jacob and the nation of their fleshly descendants. Likewise, the Greater Moses, Jesus Christ, is not the Mediator between Jehovah God and all mankind. He is the Mediator between his heavenly Father, Jehovah God, and the nation of spiritual Israel, which is limited to only 144,000 members. This spiritual nation is like a little flock of Jehovah's sheeplike ones.?Romans 9:6; Revelation 7:4.
A lot of JWs don't realize this teaching. Especially younger ones and newer ones. If put on the spot they'll say "Jesus" is their mediator. There are some that will remember the correct teaching and answer as the WTS teaches, however, they'll beat around the bush in doing so. Even then all you have to do is say that the Bible says "There is one God, and one mediator between God and men, a man, Christ Jesus." (1 Timothy 2:5) . How is that the Bible says one thing and JWs say something different.
