it has nothing to do with giving birth. it's just how you call your female parent. that's the dumbest thing in omegaverse and, honestly, omegaverse has a lot of dumb things. it's fucked up how they keep giving omegas a female role while at the same time presenting them as inferior, weak, dumb, only a sex toy who goes on heat. someone who is not capable. it bothers me a lot. some magakas really try to change that stupid bullshit.
Mom has nothing to do with sex it just so happens that the majority of animals that give birth are female so it's associated with females. However, Mom means the one who gave birth to you! That’s why children DON’T call their aunties, sisters, females teachers etc Mom because even though they are female they did not birth them. That’s why adopted kids are not obligated to call their female adoptees Mom either cause they’re technically not their mothers. So if a man was to give birth they would technically be the child’s mom!
you comments makes no sense. if a adopted child is forced to call they female parent mom and not his male parent even if is a gay couple or a single father, it means the word is for females. it have nothing to do with who gave birth to you. is a word to identify the gender in a job that have male and female. pretty much like a king and queen.
Then what would you call a male who gives births? Dad’s don’t give birth! So calling them that won’t make sense. How would they differentiate who gave birth between the couple? I watched a documentary on how male seahorses give birth to their little seahorse eggs and they were coined “Mr Moms” in the documentary. They’re one of the only two males on earth capable of giving birth. They even used the term “mothered” to describe the male seahorses laying their eggs! The same would apply in the omega verse! Also, by omegaverse law Omegas have a womb just like women do, they’re have both attributes of a male and female why would you want them to adopt titles only associated with men when their bodies are half male and female?
OP, everyone who has replied to you and tried to argue with you has brainworms i swear to god. i also don't like the "mom" thing and here's my reason why: the inherent idea that a man can't give birth is transphobic.
there are trans men who have given birth. there are also people who have given birth, and then realized they identify as men. a child would not still call that person their mom, because "mom" is a gendered term. trans men do not want to be called mom. if you want to be super pedantic about it, google "mother definition" and you will see that today it literally just means a woman that is raising children, whether or not they're her own, that's it. to reiterate, the people arguing that mom = someone that gives birth are transphobic. it's 2020, you should know better.
Wait. Did you just compare transman to Omegas? Transsexuals change their sexuality! They change their names, pronouns and so on to fit who they are comfortable being. However, Omegas are an independent sex, their situation is completely different from transsexuals. In case you don’t know, they are one of the 3 sexes in the omegaverse, thier constitution being both female and male! Because of that they borrow both attributes of male and female, pronouns included unlike transsexuals who completely forgo their previous sex! In fact, for someone who is proTransexual it’s of ill taste to assume what pronouns should be used for Omegas! Never once have they complained about being called mother! If they’re are comfortable with being called mom then who are you to say they’re wrong? Would you tell transman who still allows their children to call them Mom as wrong? Because their are still transmales who are called Mom and transwomen who are called Dads! I have a friend who’s father is transxual and she still calls him Dad! Is she wrong and is her father wrong too?
What a huge speech about respecting what people want to be called even if it’s outside their sex yet you condemn male Omegas being called Mom! Doesn’t that go against everything you just said? If men want to to be caller “her” then so be it, if male Omegas want to be called “mom” then so be it! Why would you restrict the pronouns someone should use based on their sex? Or are you saying unless the omegas surgically remove their dicks and grow boobs would they then deserve to be called moms? Who are you to make up those rules? You can genuinely see how happy and bright they are when they’re called Mom by their adorable little ones. But because it doesn’t suit your taste then they can’t be called Mom? Let them be called what they want!

his dad, not "mom'. i hate in omegaverse when they call omegas "mom" even when is a dude. i only read one manga that didn't go with this bullshit. (megumi to tsugumi never fails to be superior).
