Diabetic people and people who rely on ventilators are sentient and aware of their surroundings, and as born citizens they have the right to life. Fetuses do not possess either of these traits for the majority of the pregnancy, with the possible exception of fetuses in the third trimester, when most abortions are illegal anyway except for medical emergencies. In the event that a born, legal person becomes incapable of making decisions for themselves due to illness or other incapacity, they may leave a living will beforehand detailing how they should be treated, and give another person permission to make health decisions for them. Fetuses cannot do this, because there was no sentience capable of making these decisions or being aware of its surroundings in the first place.
1. Nobody gives a shit what you think.
2. There is no such thing as "natural law," and
3. Your appeal to nature in and of itself is fallacious, and is known as the naturalistic fallacy.
4. The definition of "marriage" and "homosexuality" are not contradictory. They are not even remotely related. One is a religious, social, and/or legal union between two partners (or more in polygamous countries) recognized by law. The other is a sexual orientation.
1. English orthography is a bitch (you can blame the French for that), but if you've learned the language right then you can deal with it. I don't hear any kids in China complaining about the pitfalls of a character-based system, so if they can do that then I think you can master this if you just put your mind to it. Language doesn't change just because you can't learn it.
2. Even if you managed to eliminate the use of the letter C for the phonemes /k/ and /s/, you still need a letter to represent the phoneme /tʃ/. "Ch" is almost always pronounced /tʃ/, so I don't think it's necessary to find a new letter, but if you wanted to reduce all the sounds in the English language to one letter, then you could always just use... well... "C". Lots of languages do that. No reason to commit genocide against the entire letter.
3. Overall, trying to reduce English orthography to be strictly phonetic is stupid because dialectal differences will cause more confusion in the written language. (For instance, should "bottle" be spelled bädl or bätl?) I once tried to converse in IPA with an Aussie once, and it was very frustrating.
