I don't assume lending an uterus to be a more life changing thing than what fathers have to do (law enforced) for a child, when comparing the effect with the 9 months uterus lending plus a from-the-birth-bed-away adoption. And it is as well a kind of responsibility you can't get otherwise. So fathers have by law enforcement higher burdens to shoulder for a pregnancy than mothers (which are none at all, if you assume that abortion is unregulated). To make it similar, you can chose, if fathers get the right to just run away if the mother wants to get the baby against the will of the father or if they can demand the mother to abort.

Although I disagree with you, I can accept when people don't think embryos are humans. I can't accept that people find it OK to kill them, if they assume they are humans.
One of my arguments for protecting embryos is the eroding of respect for life, so if you feel insulted to be compared with an embryo, it is unlikely that this has consequences in other cases, and it is unlikely that you have this opinion only because of convinience.
