Although this is, how it sometimes works, I would be very uncomfortable knowing my partner is about to become a biological parent with some other woman I met and would flip out if he planned to continue being involved with them and the child. Especially, if they plan to tell the child. You don't know, how they would react and if they choose to see him as their father. Making a child with another woman and being involved in their life while already being in relationship with a partner, that's not ok with it, is not alright in my book and would be a deal breaker for me. If you want to. Anonymous donations are one thing, emotional involvement is too far.
your own insecurity aside, donating doesn't work like this it gets no emotional involvement from someone who's mere stranger to the family that happens to help in sth they couldn't. the kid grow up to their two dads/moms and that's it, it's 2021 no one is getting special treatment anymore just bec of some fucking genes/blood if you aren't the one who's always there for the kid and taking full responsibility raising them with your partner, you get nothing with the kid and the kids themselves know well the ones who put them to sleep and wake them up the next day with gentle kindness, are their only parents. you don't wake up one-day wanting to get a DNA test and tracing who your actual parents are
besides, going by your wanky logic kids with anon sperm donor should be also wanting to search for their biological parents however their search wouldn't be as easy as the others. damn I felt so stupid writing this shit imagine (trying) giving a birth to a kid, raising them the best you could with your SO then out of nowhere "I'm -other partner who has no biological involvement- not actually your parent but that whatever human who has nothing with your life but happened to have same genes haha"
fucking yikes, learn more about rl gay couples outside of your totty-potty 'yaoi'
Did you even read that chapter or just came to the comments, because you got triggered? Alex clearly stated, he would hang out with the kid and they do know the couple. You can ramble all you want, but you're the one, who has trouble comprehending text that's written in bubbles and gets mad at people, because they are talking about a specific scenario and not your hypothetical one.
I do not care for your "I think this is, how it works IRL" shit-news check it works very differently in different part of world, so you still wouldn't be correct), this a comment section for a manga and we're talking about the scenario, where the character does plan on being involved and how we all would be uncomfortable with that, not a scenario of anonymous donations to strangers. I don't get, why are kids like you even allowed to read 18+content, when you clearly can't even read well.
On the IRL note, you should feel stupid. My friend works in adoption cases and nearly every child wants to find their bio parents and connect with them, get their approval, anything. They might have been raised by their adoptive parents since they were babies and they do love them, but once they know, they have bio parents somewhere out there, they long to connect with them. Learn more about children psychology and human psychology in general, as we all have ingrained need to know, where we came from and how we came to be. That's why many countries have laws that children the right to know their biological parents. Also learn about adoption, donations atc. outside of your country, if you want to preach, or even better don't rant about hypothetical IRL scenarios, you are, despite all the big words and proclamations, clueless about in a comment section talking about a specific fictional characters.
Ur whole attitude screams straight girl so ye no need to project ur straight fantasies on mlm and think this is how it works, "straight girl" since it gets u so mad lmfao
More like wait lol what reality u living in where gay is no longer used as an insult?? What rock are you under i bet u think straights are oppressed
why y'all making big deal of alex being a sperm donor when that's how all gay couples with biological kids work (sperm donors/surrogate mothers) touch some grass your omegaverse doesn't exist and this is how reality has been for many, and it's perfectly fine
