Okay, thanks for your responses everyone. I'm glad to see the majority of you do see the problem here - not that many people on the forum are involved themselves, just a very small minority.
I guess to sum up, play how you want. I don't like time-travelling, I would never time-travel, I do think it goes against the game (personally) but I wouldn't judge someone for playing the way they want to (as long as you're not spoiling major things just to show off, obviously - there are some people who do that.) There's no need to write any nasty comments on YouTube or make someone feel bad on Twitter in any way because they decide to play the game a certain way - in no way does it affect you.
As for the headcanons - same point, really. Think what you will, imagine what you want. But don't force people into having the same thinking as you, and accusing them of things if they don't. It's nasty, and brings out the most toxic part of the fanbase. It's cool if you choose to see two characters in a relationship, whichever way (gay/straight), however else. I just don't care, and a lot of other people don't care - we just want to play the game without having things thrown in out faces for not agreeing with you about a certain point.
Just please, all be nice to eachother (I know the vast majority of us in the forum are awesome, really) - this is mainly a rant to the toxic side of the Twitter community, and also I think you see it a lot on the r/AC_NewHorizons subreddit, as well. Let's just all enjoy the game, have fun, appreciate the amazing hard work of the developers at Nintendo that clearly put their heart and soul into making the game (obviously, critique where there are short-comings too, haha - just don't be nasty in the way you criticise. There is constructive criticism.)
I think (and I hope) that after a few months, and the community has settled, and people have stopped obsessing over getting certain villagers no matter the cost (god forbid...), things will get better, and we hopefully won't have to complain.
Sorry for the long post. I just really needed to rant, because it did genuinely upset me the way that other communities were looking at us in a negative light (quite rightly) because of the way a small percentage of people have been behaving in the community. So let's calm down, and all enjoy this awesome game.
(I would appreciate the thread being locked now, I think all that has been said that is needed!
