Ah...another day in banana republic USA. I couldn't be bothered to read the 2 pages (sorry), but I'll just take a stab at the OP for lulz sake.
I mean, if you're protesting to protect a tree why not protect a human life?
Trees are full grown. You probably didn't mean to imply that others don't want to protect full grown humans, so Ill brush that of as being a dumb analogy. The correct analogy would be "if you're protesting to protect a weed, why not protect a fetus?".
...to which I would reply: this is 'weed' in the sense of those starting plants that crop up anywhere, not 'weed' as in marihuana. Nobody's protecting the former kind.
If you are having sexual relationships then your are usually taking the risk of becoming pregnant. Not ready to be a parent - keep your pants on. Of course, there is the minority of people who are impregnated against their own will. Rape sucks, but murder is murder. Rape usually doesn't result in the baby being mis-figured or deformed (which is the case if someone in your immediate gene pool - which happens in even less of the situations).
I...Honestly can't tell if you're playing devil's advocate here. Considering you make the statement that women are better positioned to judge on the matter, I'd think so. But then why add that sense of twisted logic?
We already fail children in so many ways, but at least give them a fighting chance!
The idea is that if you get rid of the unwanted children, the actually wanted children have a better fighting chance. You repeat the "it's murder"-line a lot, but considering you trip up on your opening statement (even if you consider fetuses life, at least acknowledge that it's not an universally shared belief) I don't think it'll convince anyone thinking otherwise.
Here is what our President said about the issue ...
Sorry, but this is where I tune out. This is a triple whammy of strong skepticism:
1) republicans never really cared for abortion, but use it as an argument to draw in votes with religious folk that are too dumb to realise that republican's main goal is to lower taxes on the rich.
2) Trump is a known liar. That doesn't make him wrong per se, but you really want to dig up someone more credible if you want to make a statement.
3) Trump is also a crook, and on the brink of being exposed as such. As a result, anything controversial that gets thrown in the ether is more likely to be because of "this way, less attention is spend on my government" reasons than "I actually adore life, no matter how early" reasons.
