If the "guest" refuse to leave, you can throw it away.

The consequences to an unwanted pregnancy is having to make a choice to continue or finish it. The fetus doesn't have a right to the woman's body. The fetus doesn't have the right to use the woman's body to feed or develop against the woman's will. When you claim that she should be forced to pregnancy and birth, you are basically arguing that the fetus own the woman's body and that she should be a slave to the fetus.

Adoption doesn't magically transport the fetus to an empty void until it magically appears already born without the pain and risk of pregnancy and birth. And giving birth is one of the most painful experiences. Forcing someone to go through that is basically torture.

You don't like analogies because all your arguments try to circunsvent the fact that the woman's body is being used against her will. That she is denied ownership of her own body.

But if deny the use of her body by the fetus is murder, whenever a man denies the use of his blood and other organs to save other person life it would also be murder. Do you know that still borns need blood donations? Why aren't you arguing that man doesn't really own their bodies because fetuses need blood transfusion if they are still born?/s

The moment you accept that a woman is a person and has a right over her own body, you have to accept that she can chose, wheter it is adoption or abortion. So can choose pregnant trans men. But until a pregancy can be transplanted on a cis man, the man could only give his oppinion, not impose his choice on the pregnant person. Same with women, only the pregnant person can decide.
