It’s not something people should get mad over if they’ve actually read the manga. Haku flat out said: If you have a kekkei genkai, you will get judged. The Senju already had a prejudice against the Uchiha, but dear old Tobirama thought it would be lovely to make it worse.
Rock Lee: Bullied because he couldn’t use ninjutsu but wanted to be a shinobi
The Bijuus: Treated as bombs when under hot water but they are scum otherwise.
The Hyuuga: The land of lightening tried to kidnap Hinata and snatch her eyes. THEY ALSO tried to kidnap Kushina because she was from the Uzumaki clan.
8 ways to Sunday if you have something that sets you apart from the fray, you will get judged. And the Uchiha got the brunt of it all thanks to some butthurt brother of Hashirama.
Ever wonder why it took so long for Sakura to get some skills? Because she doesn’t have anything that sets her apart. Yes, she is good at genjutsu… But ya’ll forgot about Kurenai tho…
Yes Sakura is a medic, and a student of Tsunade. But ya’ll readily threw Tsunade to the side and forgot alll about Shizune tho.
