Completely but.. the majority of people criticizing the game aren't posting spoiler or threatening anyone, they are people who know what they know and don't want the game now they know what they know. Its not taking a stand against anything, its simply "I'm not buying this because I don't like it". No more, no less. As usual with the internet its a very vocal minority (the opposite vocal minority, going around calling everyone phobes etc...) There is a much, much bigger section of the fanbase not happy, they aren't throwing spoilers, ruining posts and threatening anyone that is a very vocal minority.
They are simply voicing their opinion in the way I am by saying "I know what I know and this is rubbish". It's like the GoT thing all over again, where the majority of those not happy with the product get lumped in with the idiotic minority who behave like tits.
People are perfectly entitled to voice their anger when someone takes a shit all over characters they've enjoyed. They aren't entitled to be cnuts about it though. Everything is open for criticism.
I get that no matter what ND did with the game some people would simply be furious and a loud minority were just waiting for an excuse to attack Druckman over Ellies sexuality but most people don't give a shit. I would say less than 5% of the criticisms I've read have being what you said in your original OP.. my very reason for quoting was - And all this "I'm not buying the game now after what I've read" bollox is coming from people who, 90% of them, weren't going to buy the game anyway. - hence why I gave my opinion on it and that of almost everyone I've talked to who feel the same because the bolded is completely false. People that love TLOU aren't picking up the game, its not taking "a stand" or any such nonsense, its "I've seen every cutscene in the game pretty much, in order. I know exactly whats happening and in my opinion its a rubbish plot that spits in the face of the series fans. I'm out".
Edit: I really hope you enjoy the game, hell I hope the gameplay is so good that I have to go and buy it myself.
