Incubators come about after birth. Birth would have still happened. No one is arguing they are not people, as they are recognized as citizens and as people at that point. It would in fact be that point that their age is even calculated, at birth. There is a point where if a fetus is born, they will not survive after birth, regardless of the incubator though. And doctors do not consider it ethical to induce birth on a 50% chance that they might survive if they utilize limited hospital resources and likely some major health issues.
A pregnancy is absolutely an invasion.
I'm asking for evidence, not your claims. You said "very late term abortions", which is not anything I've ever heard before. "Late term abortion" is the normal claim, and that can be either after viability, after 20 weeks, or after 3rd trimester starts, but I don't know of any bans that begin only after the 3rd trimester starts at the moment. But it doesn't matter because they are still allowed in almost all those states that have a later abortion cutoff that they can abort for more than just life of mother. Almost all also allow for severe fetal problems and health of mother. This still doesn't cover necessary events though, such as "health/life of another fetus in same pregnancy".
