Fuzzy ? No. The theologians think this way. Educate yourself. Read humane vitae
I’m not wasting my time reading your source material. You said birth control is abortion. Condoms are birth control. Therefore, by your own words, condoms are abortion. That’s what you said. You can support that or retract that. You cannot pose “what ifs” and claim they are a certainty. Any “what if” regarding the failure of a condom applies equally (and equally invalidly) to a failure of the rhythm method. Your suggestion that a condom failure inevitably leads to a abortion relies upon facts not in evidence.
You have backed yourself into a logical corner and are now struggling, lamely, to get out of this corner. You can’t because you’re wrong.
