You seem to be very reasonable, and willing to listen to people.

And I do understand where you're coming from, and that you didn't mean to offend anyone and don't want to offend anyone. But you have to understand how you and your players are coming off. You are aware that a great number of people are offended. Offended enough to spend money out of their pocket to fix things. Offended enough to come here from other sites to speak up when they found out about this. It's not just a handful of 'extremists' as someone said above, it's a large group of very real people with very real feelings and very real objections. And you have said you understand and feel badly about that.

But you're essentially saying here that you won't change the name out of spite. 'We are sorry about it, but perhaps if we didn't get attacked about the name, if people had been calm about it, then we would have discussed a change of names earlier'. Which comes across as extremely belittling, and completely negates everything you've said before about not wanting to offend, and being sorry that people are upset and bothered. So regardless of what your original intentions were, you're coming across as being irrational, childish and cruel.

You're upset that your game has been attacked, and I understand that. But by digging in your heels like this, you're not making it easy to give you some slack. You're doing the exact opposite, and only making people angrier and more hurt. Take a step back, take a deep breath, and take another look at the situation with a clear head.

And on the name and why you chose it.... There's a difference between what JKR did, in drawing a parallel and keeping it very vague and firmly rooted in fantasy and what you've done here, and not keeping those parallels firmly rooted in fantasy. By all means, explore those parallels! But perhaps a better way to do so would be to remain true to the spirit of JKRs works and preserve the fantasy, not the reality.
