One of the major things the watchtower teach is learning religions and how important it is to find out if one is catholic or Baptist or so forth.
I can recall when I was studying with my ex-inlaws in the blue, "truth," book, there's a chapter on, "Why Is It Wise To Study You're religion." There you'll discover it covers just a few tibbits on most major religions. A few favorites are easter, christmas, and a few others. I knew where these things came from. I needn't need a jw to tell me about it. Then they'd go more into a person's religions.
Now days when I counter a jw I just tell them I'm a christian. Since a jw doesn't understand what a christian is, they try to identify you by asking you about Mary, mother of Jesus, or do you believe in the spiritual gifts, or miracles. I've discovered that, that way they(jws) can identify what religion you are. Or they ask what church do you belong to.
I just tell them that I may attend a local Baptist or pentecostal church. Or may attend a Calavery Chapal which is nondomination. Of course they might try to start a discussion on Baptists or pentecostal. I stop them from the start.
I explain I'm nondomination and I have a deep loving relationship with Christ not a religion. Many religions may have their short coming and I don't get involved in their legalistic debates and Christ has no faults. Plus Christ will never tell you one way or another you're dead wrong. Christ tells us how to follow Him and explain His adversary. Then I explain that in order to never error, follow Christ.
Of course trying not to error is a life time job, but at the same time if and when we do error we are christans and seek His face to repent.
I have no religion. I have faith in Christ. And one of the main points on being a christian is, Christ told us to follow Him not a religion.
So for those who study with JWs, you'll discover you're really studying the Watchtower principals with a few bible quotes. And if you ask them about it, they may say things like, " If you are going to become a citizen of a different country don't you study their ways?"
You say yes, but isn't it more important to learn of Our Savior Christ Jesus and study the gospel, then a man made organization which is known to have faults? Of course they may fall back and tell you that many religions fall short. Then you can explain to them many of our christian churches may differ, but the messege is clear......Christ Jesus is our one and only Savior.
