My "opposition" doesn't care about phoetuses or they would make sure that healthcare when pregnant is free. Neither they care about "murder" or they would ban anything that could produce miscarriage. Yet, they don't.

They simply asume that the phoetus can use the woman's body regardless of what she wants. If the phoetus weren't using the woman's body, it won't matter if you remove it from the uterus. That is the thing, you can't use another person body. No, not even if you are a phoetus. The woman is not murdering anyone, is removing something from her body. The fact of that something fully depending on the woman womb, blood and body to feed and develop doesn't change that it is in her body. That is what body integrity means: other people/things can't use your body without your consent. No, not even to feed or develop. No, not even if you would die (otherwise, people would be forced to donate blood, marrow and organs).

The again, the problem is that the "opposition", doesn't consider women people.
