Yurifans are delusional and rabid. If you drew two stickmen and labled them both girls within minutes you'd have a goggle of them show up to argue "clearly yuri", "best yuri ever" followed by manic derogatory comments about "het romance".
Generally it's best to avoid interacting with them or attracting their attention, however they're an easy scalp commercially since they pay out the wazoo for even a hint of anything girl on girl.
I'll probably receive hate for daring to write this but where is the lie?
