If parents decide to have a subhuman kid or any kid, honestly, they should make the proper environment for him. This goes double if both of them are not good-looking, and there is a big chance that their son will be subhuman. What they are supposed to do is compensate for his looks, because they can have a massive impact on his upbringing.
They can compensate for his height very easily by giving their son HGH. Also, they should be very rich, as it is very important to have at least something from the LMS. No one is going to live an incel life if they are born into wealth. That will have a massive impact on his upbringing and the respect that he will get from others. Now don´t mention ER, because he was not particularly rich; his family was just well off, but he did not benefit from it that much at all. He was not supported by his parents.
An incel son needs to be at least a millionaire to offset his inceldom. This is something that parents can do, but bringing a subhuman to this world and then telling him to earn his own money and work for his whole life without even experiencing any kind of happiness on top of that is just retarded.
