I genuinely can't distinguish schizo posts from troll posts any more, but I'll give you the benefit of the doubt that you're a sincere schizo OP and share some old wisdom that stuck with me since I first saw it posted here 10+ years ago
Your instance of your waifu is unique to you. No one else can take her from you or change her. She is your ideal, isolated solely in your own mind. You are hurting yourself solely on other peoples' instance of a similar exterior design. They are not the same character. No one can change the characters' instance in your minds eye. If you believe she is pure, then this is an unviolably true fact that no one can change; not even the original author of the character.
This is 100% an easily fixable mindset issue. Someone may love Sanae the gamer girl with dark green hair that loves retro games, pure and is madly in love with (You). Someone else may love Sanae the gigaslut gyaru with blonde hair. The only similarities these characters have is sharing a superficial template, but it's not *your* Sanae. Hope this helps.
