[keep in mind that this person identifies as an irl yandere themselves ]

I wonder...

Why is it that people think it is "cool" to fake being a "yandere"? I simply cannot fathom. Have they ever been truly stalked? Have they stalked before? It's a time consuming effort on the stalkers part. And, if you are a stalkee, why seek out such self-destruct behavioral habits?

On a flip note, do the people who purposely seek out a "yandere" to date genuinely believe the "yandere" they found is legitimate? If you found them over a "Yandere Dating Discord/Site/Forum/Ect" - are you honestly in belief that they are real?

As a stalker (with consent), I can tell you with 100% positivity in my words that they would not pursue you the way a "yandere" who chose you on his/her own would.

*Note: I mean no offense, I am simply in disbelief. If this can be rationalized, please help me understand.

Because people are dorks who like to imitate anime?

Hnn. Imitating it is one thing, but some lines should not be crossed. I believe some delude themselves into believing they are truly a "yandere"
The difference, IMO, is the line of reality. If you do such behaviors in real life, you will surely end up in prison eventually.
