I'm not quite sure of what you mean by a straw man and a non sequitur.
Is it a straw man or a non sequitur to point out the the US government has no Constitutional authority to define a spiritual event? Or is it both?
It seems to me the question is exactly on point.
Is it a straw man, a non sequitur or just stupid to agree with you that mammalian life begins at conception? Did I err in noticing that to use this as the sole criteria means that a human is spiritually no different than any other mammal?
Do the techs in either the in vitro lab or the embryonic stem cell lab just scoop up all the material in the petri dishes and hope they got a live one?
Nope, they use the exact same techniques they use to genetically engineer better pigs.
We are better than pigs because we have souls.
Show me when exactly a soul picks up a body.
Noone has to prove the existence of the soul to justify laws against murder or the use of regulated material and licensed personal for the purpose of killing or putting human lives in a state of mortal danger.
If we must prove the soul exists to prove that a person is a person, how do I know that you are a person?
