How can discussions on other religions begin when the Christian segment overloads R&S with repetition?

they are programed and not capable of giving a rational explanation for anything. this, in my opinion, is because they feel that they must answer as a christian and not a rational person. even though they might have doubts or questions about their religion they are forbidden, by the bible, to ask or wonder or question. therefore they respond with scripture that does nothing more than place more doubt on the validity of christianity. i have asked questions before and instead of getting an answer or simply an "i dont know i just chose to believe". i got tons of scripture that. and people saying i was goin to hell for asking. the sad fact is that most christians are not speaking for themselves. they are just giving answers that have been programed in them. there is nothing wrong with believing what you want, but when a religion, government anything in power, does not allow criticism or questioning it becomes corrupt. and it keeps its followers ignorant because they are easier to control.
