Yes, there is no merit in understanding the nonsensical logic of religious dogma. Their logic is all the same circular bullshit of "God says so, cause it's in the book, that I know is true, cause God said so in the book" when boiled down anyway.

Instead, we should be understanding human psychology and what drives people to believe in the superstitious and trap themselves in fallacious logic while dismantling the current institutions that abuse this flaw of human psych for their own selfish ends.

The reason they can use it to oppress people is because people give it legitimacy and treat it as a valid belief instead of the superstitious nonsense that it is.
