There is nothing wrong with critical thinking. You just need to study to see what something really says before jumping to conclusions.
You actually come across as quite a rational Christian sort, but sadly in the minority of my own experiences with them. I do have a question for you about one (of many) parts of the bible. Sidestepping the issue for a second of the patriarchal deity who drowned his children. can you shed some light on this bit below please?
"But as for these enemies of mine, who did not want me to reign over them, bring them here and slaughter them before me.’” Jesus Christ. Luke 19:27
Perhaps you can help me with critically considering the idea of preaching forgiveness and thou shalt not kill but practising another. Or is this just an example of a remarkably flexible rule set?
