Nah, trust me, you don't want a brother to fight with. I have some PTSD from fighting and running away from home once.
I'd rather just be born as a girl and have a sister, that'd be so much better. Instead, on this timeline, I have been diagnosed with depression (and undiagnosed CPTSD).
My childhood hobbies consisted of runescape and fighting my friends brothers and other kids (most fights were mutual). Some people just like fighting. If I had a younger brought to fight with I would be very gentle and fair.
I do but I win every time and she fights cheap as shit. Pulling hair, biting, scratching. Its just playfighting you dont need to cause permanent damage.
This is just people who don't fulfill someone else's idea of who they should be so they feel they're the wrong person.
If you're less insecure and more confident in yourself and accepting of who you are, that would be the difference that makes you successful. Not "I grew up with a sister" or some other incel bullshit.
While there is no question that in modern times, both in the West and East, the term lolicon refers to a sexual attraction to underage girls, that's not how it started. This topic goes all the way back to the 70s and the shoujo manga scene which was initially dominated by women, and only later welcomed men.
As with most things in life, if you actually spend the time to look into it, these things are a lot more nuanced than you might think.
