Yeah I think the gray area is what made me want to make this post, but it being a gray area might be the most satisfying answer I get.
I looked through about 50 comments and didn't see any comments positive towards the event, could you show me what you mean? Or did you mean a comment that was supportive of lgbtq? The closest I found is "I'm all for gay pride but it has no place in runescape" which is perhaps not hateful but misinformed. I think it's a bit unfair to say this video was only searched by those looking to express dissent as this creator gets about 10-40k views on their videos just in general (during those years). If anything this video underperformed which would mean people are not seeking it out.
I would probably agree there was a decent amount of counter protest, but most people who disliked the update just begrudgingly ignored it, where if someone feels like their friends way of life is being protested against, they're more likely to turn up.
The pride event was on I think 1 or 2 "worlds," where each world has a limit of 2k people and there are about 150 worlds. It was also scheduled to start at a certain time, and this looks like the beginning with the most people. The protests against the event were on uncoordinated worlds with no set times, people were live streaming it and the size of the protest crowd remained essentially the entire day (with I don't know how many/few on other worlds). This is just to say I feel like exact numbers aren't comparable, I was just showing there are a large amount of players that are angry enough to actually protest it for hours. I could maybe find one of the streams if you'd like (for the pride event and for the protests)
Speaking of the comments on the video, someone posted this (I'm not sure how reliable you'll find it, but this is what I recall being the case too)
This was a poll done on a live stream, so obviously not a full player base sample. I suppose for me I see the player base as not wanting change and being stuck in the past, quite literally people will say this skill in runescape is terrible but I had to do it so changing it now is unfair. This to me is basically right in line with slightly right leaning, as they are using the values of 20 years ago when they started playing to make decisions today. Not truly hateful but just stuck in how things were before all these "politics" got pushed into their game.
I think you actually did kind of answer my "gray area" question with all that. You're going against the wishes of the many for the good of society as a whole, which is unfair but what's the alternative? lgbtq+ people aren't allowed to exist? humans are resistant to change so sometimes you have to force it on them for anything to improve.
I think I would argue that most of them aren't hateful, I think especially in this case most of them are just in the mindset of "this is weird and irregular and I don't want to deal with it" and another portion says "this does matter but I don't want to see it in anything because it makes me feel uncomfortable." Neither really hateful, but if you have 0 exposure to something it's going to seem weird and scary. They don't want to see it because it's unfamiliar and it's unfamiliar because they don't want to see it. Definitely a large portion has some hatred mixed in, though that too might just be because they don't have a single friend who is even partially involved with minorities.
What you said about needing to be in a good place to stop being hateful is true in I think even more ways, such as just the way you communicate in daily life. I used to think similarly to "I don't care but don't shove it in my face" so I get where these people are coming from, even if it is misguided.
The demographic of osrs I would wager is 50% people who are just addicted, most polls I've seen run by creators have people saying they are somewhat unhappy and are just addicted to the game (it's pretty similar to cookie clicker, just with a game built around cookie clicker mechanics). That's why I don't think these people are hateful, they're just me back when I was a lot younger but never had the experiences I did that changed my mind. Maybe I've just been lucky enough to not meet many truly hateful people.
I don't think this is unreasonable but how far would you take It? If a game was actively promoting hate, and is an mmo where the majority can sway your thoughts, and this game is constantly teaching you to be more hateful but the players keep voting to keep it that way... I don't know at some point it seems like it becomes too much of a negative.
