Nya-chan. I don't think it's that fact that you're criticizing the manhwa but more about how you are going about it. Seems like your word choice and use of definitions is the main culprit. Then you have this idea that FF should be realistic because A happened so now obviously B should happen and it should be depicted. To me you sound like you're saying FF is terrible because it's not realistic but then compare it to another like Their Story which isn't realistic either. So my question is, what do you expect out of this story or better yet, what do you want it to be? Because as far as I know, it doesn't present itself as, "the most realist Korean lesbian manwha ever RAWR!!" but you make it seem that that is how you want it to be. So I go back to my original question I posed to you a few pages back, why do you read fiction if everything isn't realistic enough and or too cliched? I went and read your previous posts and you seem to float between not realistic enough or enjoying the non-realisticness of a story. Thus, I really don't know why you're having problems with FF but not with Their Story.
For example:
In Their Story, they first "met" when they were passing through the sliding doors of a quick stop/7-11 and tried moving past each other only to go in the same direction. My thought was, "how did they not see each other approaching the other side of the sliding door and not move out of each others way O_o?!" and not, "OMG SOOOOO CLICHED and UNREALISTIC!! ARGH." This is how you are coming across with FF. The women if FF literally met in the same fashion and my thought was, "how did Seol-a NOT SEE NO-RAE standing in the middle of the hallway and bump into her?! O_0. I mean, that place wasn't even crowded." Both are cliched and overused tropes in one sense or the other and while kinda boring they're not that big of a deal. (That's ignoring the fact that they've been used in tons of live action movies and tv shows as well.)
Also, we are not censoring you. There is a big difference between telling you, "your opinions are trash so shut up" and arguing your points and disagreeing with you. If you really think this forum is that immature I suggest you read the Citrus and Feelings We Must Endure threads. Both have raging debates and some excellent back and forth, never once do I remember people trying to censor each other. Hell, I went from hating Citrus myself to having my points argued and disagreed with quite thoroughly and read a few other debates between people who liked and hated the story. So, I stepped back, reread Citrus, and now I am more tolerant of the story than before. And who knows! It might become a favorite of mine in the end * shrugs *.
TL;DR:
All I'm trying to say is that no one is telling you to shut up and not voice your opinions and criticism. If they are valid then the reactions will be much more mixed and some might even agree with you despite them really liking the story. However, if they seem like they don't make sense within the context of the story then yeah, people are going to oppose you rather harshly because your points are that. They don't make sense.
