What do you mean when you say that halakhic decisors do not understand dangers? And also, the source for the danger is from the Talmud — do you think the Talmud is just trying to frighten people and there is not really any danger?
Regarding the ignoramus, according to the view that it means someone who is not careful about the commandments.
What is your opinion about a religious person who keeps the commandments but has lapses, like in matters of physical contact, malicious speech, etc.? That is, someone who tries with the commandments but is not careful at the level of crossing a highway. Does such a person fall under the category of an ignoramus? If so, then many religious people, even those who make it to the study hall benches, would seemingly fall under the category of ignoramus. (I don’t want to say most.) How careful are people not to speak malicious speech? Or is the matter of refraining from physical contact more severe than malicious speech?
And if there is doubt about a kohen’s lineage, does that mean there is no need to be concerned? That is, is the unclear lineage what determines it?
Or is it that there is a chance the woman really is not from kohen lineage, so you were “saved,” but if she is from kohen lineage then the person does enter into a concern of danger despite the doubt about lineage?
I would be glad for your answer.
Thank you very much

I do not know whether the Talmud only wanted to frighten people or whether it really thought so. But from my perspective that does not matter. The sages of the Talmud had no way of knowing that, and therefore even if they really thought so, that does not mean it is true. The Talmud also contains various remedies, and they apparently do not really work. The Talmud has authority regarding Jewish law and norms, not regarding facts.
Every person fails from time to time, so that is not a measure of an ignoramus. What the measure is is hard to answer, and there are differing opinions on the matter. I think a reasonably religious person who fails from time to time does not fall into that category. I do not know how to give a more precise standard.
The doubt about lineage is an additional supporting factor for leniency. As stated, in my opinion there is no danger here, so at most this is a prohibition or a recommendation not to do it.
That is what I have to tell you. I think it is not worthwhile to be too obsessive about this issue. You are expecting a mathematical answer, but there is no such thing. And anyone who gives you such an answer has no real basis for it.
And in closing, I think the concern about punishment in the heavenly court for the transgressions you describe is more serious (though even that is not certain) than the concern about the consequences of marrying a kohen’s daughter. Sexual prohibitions and malicious speech are more severe than an ignoramus marrying a kohen’s daughter. Therefore your approach seems to me inconsistent and illogical.
