This tangent about offensive youngsters strikes me as being out of place. Sure, there are rude people out there, thanks in no small part to anonymous internet toxicity, but I look at this issue specifically from a gameplay perspective. You can't control anyone's attitude, but you can try to show them that there may be better ways to play the game. The choice is ultimately up to the individual player, of course.
There is a fairly huge difference between discussing on these forums how healers who refuse to DPS as a personal choice are not playing well (objectively they just aren't) and calling out individual players in an abusive manner. While some posters here are clearly exasperated beyond the point of being tactful or polite, there are at least as many posters who jump in specifically take offense at the notion that anyone should dare suggest that they aren't doing an amazing job by amputating part of their kit. Just recently we have this gem:
Clearly someone either hasn't actually followed this thread, is cherry-picking it for the parts that offend them the most, or doesn't care to have an actual discussion about gameplay. These kinds of arguments go straight back to healer entitlement, which is just as toxic as this "DPS-or-kick" elitism that is allegedly rampant. It's the debate equivalent of picking up one's ball and going home.
