Depends on what terminology you're using. In Biology a child is only considered a child
after birth. The layman vernacular sometimes defines a fetus as a child, but considering that vernacular is too loose to particularly care about accuracy, I often use the "clinical" definition.
It actually is. I don't know which specific analogy you're referring to so I'll say it's the toddler one. A toddler is not a fetus, it does not rely on the body of the mother to survive. Killing it is not the same as aborting a fetus. Allowing a fetus to live imposes on the body of the mother by default. Allowing the toddler to live does not. It merely needs a responsible adult guardian (of either gender.) It cannot be used as a proper analogy if it doesn't share any similarities with the thing you're speaking about in the first place!

Well we agree good sir, or madam!
Yes but slavery by default involves taking away a person's
personal autonomy. The slave owners aren't the only ones involved in this slavery deal, you know?
Your analogy only works if you ignore the actual slaves in the equation!!
Well personal morality doesn't mean you restrict other people's choices based solely on that. I personally find Catholic Churches who excommunicate 10 year old victims of sexual abuse because they got an abortion utterly despicable. But you don't see me going around them and getting the law to agree with me. That's their choice, no matter how much it disgusts me. Do not be so arrogant to presume that your personal feelings trump personal freedoms of other people, mate.
First of all, that meme is wholly overly simplistic. Not all "liberals" hold either or or even both positions. (A liberal is like the opposite to the conservatives, correct? Not very versed in American politics.)
Secondly, life on another planet is an entirely different field of inquiry, one based specifically on astrophysics. Scientists are merely seeing what can survive on other planets. Now let's talk hypocrisy. The pro life crowd often uses this angle and I don't understand why. They don't also advocate the saving of bacteria, which would also constitute "life" in this particular context. They don't speak up for the cancerous tumors people have removed, which would constitute "life" in this specific context. So it's very clear that they are only speaking specifically of "
human life" and not other variants of the term, commonly used by Scientists.
Now Scientists who are saying there's life on Mars because of single cell organisms are using the term "life" in a way that is both broad and actually pretty damn specific both at the same time. Which is cool. A single cell organism qualifies as "life" in the context of Scientific disciplines. However whether or not a single cell organism is
alive is actually hotly debated. Here, read this for more, hopefully it explains it better than I just did lol.

In other words your meme is deliberately twisting terminology to suit it's own agenda. Quite intellectually dishonest, actually.
Now my science is pretty **** weak, so I shall stand aside and let actual knowledgeable people tackle this more in depth than I can.
