I don't use soap just water and elbow grease.

To my knowledge I have probably killed some bacteria but I have never killed a zygote so your claim of me being more protective of one over the other is incorrect.

I simply base my actions where possible on observation and empathy.

If something looks like plankton, acts like plankton I don't call it a person.

If it looks like plankton but acts as in manner suggesting it has hopes and dreams and can suffer I treat it as a very small differently looking person.

A zygote looks like plankton, it acts like plankton I can't call it a person or ascribe human rights to it but the woman it's inside is clearly a person so I have to ascribe rights to her and any mice she may have living in her house.
