You may have hit an underlying cause of the disagreement here.
Were the people you're playing D+D with your friends outside the game as well before the game started, or were you strangers before play began?
I always assume (perhaps wrongly) that the people you're playing D+D with are also your friends outside the game beforehand, and that you already vaguely know what makes each other tick. And, that you are capable of separating in-character actions and emotions from out-of-character actions and emotions.
Yeah, gonna have to say this doesn't have anything to do with it. I'm firmly opposed to your viewpoint, and I'm also of the type that inherently assumes people are generally gaming with folks who are already out-of-game friends.
That doesn't change the fact that if someone acts badly, those friendships can be damaged. I've seen drama erupt amongst groups of gamers quite a few times, friends or not.
Its part of the problem, in fact. Player 1 assumes he knows player 2, and so starts up this in-game romance. Player 2 isn't comfortable with it, and so asks it to stop.
At which point, by your comments, you advocate player 1 ignoring his friend's feelings, and beginning actual harassment of player 2. That's the point at which player 1 is not acting like a friend, and that's going to cause problems both in the game and out of it. And that's what the rest of us are objecting to.
I don't think we can assert that player #1 is immune to OOC condemnation for 'harassing behavior' and also player #2 is immune to criticism for being uptight. I don't think you can issue a blanket statement saying that player #2 has every right to publicly correct player #1 undiplomatically, but that player #1's responce to player #2 is something more than correcting player #2 in an undiplomatic fashion. I mean, I can probably agree that neither player is handling this in the best possible fashion and with the most mature cue's, but I'm not prepared to agree which one is being 'immature' and a 'jerk'.
That's the point, though - initially, neither is. One of them is an overenthusiastic roleplayer and the other doesn't want to play outside his comfort zone. It is the point at which player one is asked to stop, and their response is not to respect the second player's wishes, but to instead respond by making it worse or taking it out on them in-character. Those are the actions that are meriting the 'immature' or 'jerk' label, and I'm not sure how one can defend it otherwise.
If the second player didn't respond by asking player one to quite it, but instead responded by insulting him and telling the DM to kick the other player from the game... then yeah, he's the one earning those labels. But that wasn't the example that we had been discussing.
Just to repeat my position - if one player engages in behavior that makes other people uncomfortable, they have the right to ask him to stop. If he feels really strongly about what his character is doing, maybe he can have the group talk it over and find some sort of compromise.
But if his response is simply to escalate, and respond by "giving him a bad time", or to "follow the advice of the mighty King Crow" and kill the character and take their stuff... yeah, sorry, you have crossed the line and are most definitely acting in an immature fashion.
I don't care if your justification is that this is just how your character would act, I don't care if you are just trying to get your friend to 'lighten up' or help them work through some perceived psychological issues. Regardless of reason, what you're doing is most definitely not cool.
I wish that we could keep gender references out of this, because I think its biasing the conversation in certain ways. I think by making the 'harrassed' character female, we are engaging in subtle gender bias, not only by making the assumption that women are more likely to be victims, but in making the other player fit into a sterotype of the geek making unwelcome character advances. Let's make this more general, and try to avoid our biases where we can.
To be fair, I've been assuming in the theoretical example that both players are male, but one just happens to be playing a female character.
Especially since Lanefan (who was largely the source of the example) made note that the other player would like be a him, since "it's always 'him's who have these issues".
Of course, I might note that this gets into an entirely new area of problems with Lanefan's assumption that female players could never possibly object to unwanted in-character romances from another player. But, uh, that's probably a topic for another thread entirely.
