If it is a stram man then why don't you try to set fire to it?
Actually, why not. I'm bored and the answer is quite ironic.
My opinion, believe it or not, is based on an argument that actually contests religion.
Let's see if you can follow it without projecting phantom "religious attitudes".
My opinion, and that is all it is, it is not a universal truth, is that the human mind projects qualities into the things it perceives and onto itself. This is a principle of existentialism, that existence precedes essence. The qualities of things are not determined by an independent higher authority rather they are defined by what perceives it.
If you had read more carefully my discussion with the example of the seed, you would have noticed my argument that the human mind projects the potential of the seed into it's very definition. A seed actually has more commercial value because of it's potential and it's potential comes from our projection of that quality into it. This is the very principle of existentialism, that entities do not hold their own qualities, they are not defined by God, rather that the human mind injects that quality into it.
Following on from this, the human mind builds qualities into entities not only with what it perceives that entity currently is, but also with a special anticipatory ability of what that entity could become. The human mind, in my point of view, nothing sacred about it, does this with all things it sees.
It views a bicycle and defines it not simply as a stationary mechanism of parts but also as a vehicle that can move efficiently.
It views a life prison sentence not simply as a punishment of a wrong-doing but also as a prevention of it recurring in the future.
It views the death of a child as more tragic not simply because it was more vulnerable but also because of the removal of it being able to flourish and become something more.
Now when I say that viewing an embryo as simply a clutch of cells is flying in the face of human thinking, this is the type of thinking that I mean. It has zero to do with being inhumane, cruel or religious.
It has to do with denying how we partly use our anticipatory abilities to define what we perceive. We do not see things solely as they currently are. We project qualities into entities with all our mental faculties which includes anticipation.
My opinion may be quite false and easy to dismantle but as you see, it's not based on religious thinking at all, in fact quite the opposite.
