You will likely never please the "pack of wolves". It is my experience that when debating with those kind of people you can present your knowledge of God and still not get anywhere. Simply because they don't want to hear it. All they are interested in is debunking your faith, they do it to antagonize and bait Christians. Most of them don't even want to learn anything about Christianity.
When a person wants to learn something, that is when they learn. A person can't learn anything if they don't want to or think they don't need to.
By all means, defend your faith! Pray about it and follow the Holy Spirit's leading. Just don't get too wrapped up in wasting time in a sedentary debate.
