Why do you guys ALWAYS change the wording from "life" to "person"? Is it an attempt to assuage a guilty conscience? The comment is "human life begins at conception", not "personhood begins at conception".
Just a side note - but for the sake of argument I will use your terminology.
So, you have pinpointed the exact time that a "blastocyst" turns into a "person", right? You know this for absolute fact, correct? No ifs, ands or buts. So, 48 days, 23 hours and 59 seconds after conception it's just a ball of cells and miraculously one second later the "personhood fairy" comes down from the sky and grants that this ball of cells is now a life.
Do you not understand the absurdity of your argument?
a rare LOL from yours humbly and truly
