OCG, you typically answer direct questions, even if you say, "I don't know."
I can find plenty of examples on this forum or others where direct questions aren't answered by people like Bible Student or Skeptic or JW or in Crystal's examples of her discussion on other forums.
It's either one of two things with most believers...
1 - They try to use a series of 'logic' traps to force a believer to admit god is real, then leave the discussion before any actual discussion happens. Like, Kent Hovind trying to get you down a path of yes-no answers to follow Descarte's theories and admit that philosophical musings prove God. Like... pinning you down on whether there is good and evil, and implying that if there is, there must be a source, and ignoring that God does and orders done all the evil things they mention in their argument (God does them in Biblical stories)
If you are familiar with what I'm talking about great, if not, dig more into it. https://www.google.com/search?q=kent+hovind+proof+of+god&ie=utf-8&oe=utf-8
2 - On the flip side, when we engage believers in discussions... if you question or point out that God is a hypocrit in the stories... or they have personal proof of God but can't demonstrate it... or if any real miracles ever occur... and on and on... you get a lot of dodging.
Why can't God/Jesus tell you the names of my first three pets?
Why can't or won't God/Jesus heal a special little girl with West's Syndrome?
Why didn't God talk to me the thousands of times I prayed?
Why is God contradictory in the Bible? Elijah tests him... he challenges you to test him with tithing... but later it says you can't test him?
Why are there so many different descriptions of how to get to heaven? If one is clearly correct, how come so many denominations disagree?
Are demons a real thing?
Are miracles a real thing?
Maybe it's not so much that Christians won't give answers, it's that most of them don't give consistent answers.
God loves me and wants a personal relationship with me... but, he never talks.
God is capable of anything and promises to answer prayer... but, he never does, he's not some cosmic genie.http://whywontgodhealamputees.com/gumball.htm
God, Jesus and the Spirit are part of some trinity where they're all the same being, but all different, and all divine... but don't know what each other are thinking, but do... but don't... Jesus literally asks God why God has forsaken him.
If morality stemmed from God, and he's the absolute source of good, then why could he perform evil acts, or order humans to perform evil acts? And if an act is good just because God ordered it, then how is Andrea Yates wrong for drowning her kids when she was so sure that God ordered it, that she drowned her kids?
God talks to people right? But he didn't have any motivation to mention to hundreds of people praying to him that a 14 month old girl was baking in a van just feet away? She died screaming... but God didn't mention to the people in the church praying to him that she was trapped out there, and could easily be saved?http://articles.sun-sentinel.com/2010-10-04/news/fl-baby-church-van-20101003_1_sweltering-car-parking-lot-church-congregation
I'm not saying you do this... but talking to most believers is a never ending dance of excuses.
