why is there a trend of women demonizing their male friends who confess their feelings for them?

i kind of get the argument, I've been in a situation where a female friend confessed her feelings for me when i only saw her as a friend, i understand the "oh shit please don't say it" feeling in that situation, and I understand it can suck, however I see a complete exaggeration of this situation online.

a lot of women think that if a male friend confesses their feelings for them that means they've been secretly plotting to infiltrate into their lives for the purpose of getting in their pants, and while that is a possibility, i feel that there are a ton more explanations for the intentions of the male friend, but it seems like this one explanation is the only one that is usually given or assumed, I just don't understand why that's the only one they go with, like most people aren't secret manipulators pulling the strings, like i said I'm not denying that it can be the case but the fact that any other explanation is thrown out the window baffles me
