People gatekeeping the word “engineer” is a bit annoying, since the word “engineer” dates to at least 1380 and originally just means someone who works on engines. “Engineer” as a legally super special class of job is a thing that came much later and only ever applied to certain jurisdictions anyway.

“Software engineer” is just a synonym for “programmer”, in the actually existing practice of the English language.

And 'doctor' means someone with a PhD. I know a lot of doctors. However, when you talk about medicine, we mean 'Doctor' with an M.D. and they are literally held to higher standards of ethics and liability. They are licensed and people who practice professionally without a license are subject to legal ramifications.

Call yourself whatever you want, but that doesn't mean you get to define what 'Engineers' are and what ethics they are bound to. Just because you use the term in your title and say it is used properly in English, doesn't mean that you won't get treated any different than someone with a PhD demanding to be called Doctor and pretending there is no difference between them an and M.D.

Of course the word “doctor” means different things, just like “engineer”. The OP is the one who was trying to conflate them. It’s like if you told someone with a PhD in CS “if you want to be called ‘doctor’, you had better be able to heal sick people”.

In Denmark you need to hold a degree of engineering for you to call you an engineer of any kind. It's a protected term. As I remember, in the US it is not protected and anyone can call themselves engineers.

It varies by state.
