Abortion is a medical term, it doesn't imply that anything is illegal or unethical in itself. The same word is used for example in veterinary science. Things that are abortions, medically, aren't going to be reclassified because that is the correct term.
That's medical language, in everyday speech we tend to use it for human-induced abortion, and miscarriage for when it's not. Including in medical settings when people are just talking rather than recording with technical terms.
All of which is fine and not hard to understand as long as you know which are being used.
Most people don't support complete decriminalization or legalization of abortion at every stage, and feel there are other issues that need to be balanced around the rights of the human fetus, and also there are questions of safety and good medical practice for the mother.
The UK already has quite liberal abortion laws compared to most of Europe. It's probably always going to be very sensitive to investigate and manage situations where they may have been breached, but it does happen.
