Spoiler: Lack of education about words and definitions

1) Why is every step sibling manga intentionally forgets that non-blood related siblings can indeed start relationship?
2) Why the hell in a lot of places in the world some distant cousins can be married?
3) Why do people call it incest? Are they so ignorant are they just plain stupid?
I've just read some reviews and comments on other web-pages, people kept bit*&ng about how immoral incest is....For fucks sakes do you even know why INCEST is immoral? I bet you know it's bad because other buzzword retards are using that word.

Spoiler: Why incest is bad

Incest is solely immoral due high risk of negative genetic mutation AND with continued incestious relationships in a family, eventually comes infertility and risk chances increase dramatically to the point where every child is a freak.

Spoiler: Step-siblings = Best childhood friends

But incest is a word solely used for relationship between BLOOD related relatives. For example in this manga if you deconstruct everything, it's not so bad. Imagine you have a very good childhood friend with whom you are almost all the time, excluding sleeping in the same house everyday. And despite many years, you still retain good relationship with them.
What are the chances of them breaking up? I think quite small, they endured passage of time, most school couples don't survive due to hormones playing and MAKING you like someone's quirks. When infatuation is gone these couples usually dissolve or other factors like long distance due to different upper education places.

Spoiler: Sex before 18

So in essence the major difference in their relationship is that their parents are living together and that they are living together. They started their sexual relationship at 16-18. Maybe i'm getting too old but it was a normal age for people to have sex when i was in school. And to my knowledge many school couples had sex in 10-12th grades.

Spoiler: Ask yourself do you have a logical answer?

Basically a general question why DO YOU CONSIDER INCEST BAD? Many people can't answer logically, most of the time you hear JUST CAUSE IT'S BAD and IMMORAL....Why is it bad and immoral? And after those question people insult you and run away from that questioning.

Spoiler: Boundaries should be clear

I can find reason why incest is bad thus i indeed consider as something that shouldn't be practiced. But as for step siblings? (Not step-parent and step-child, there is power dynamic problem and grooming problem) I literally cannot find and reason why step sibling love should be denied. If someone can answer me i would be happy to read it to this day i didn't find any logical good reason for it to be immoral or bad.

finally some educated man btw do you guys know that high risk that come with incest is so low that it doesnt matter? on first generation since it might be 10x of the normal rate But the normal rate is very small that the 10x doesnt matter the problem with incest come with the 2nd+ generation that risk get higher than safe rate
