Don't get me wrong, I'm not saying you HAD to accept it. But the message was respectful and reasonable. One of the things I hate most are disrespectful messages back in response to a reasonable request, even if it's because you disagree. If you ever want me to go full out against you on an era, just send me a few disrespectful responses and you'll have me boosting and calling upon the entire world to overthrow you. Only 2 good ways to truly neutralize an enemy. Kill their moral (which firing them up with disrespectful responses will not do in most cases) or kill them with kindness. Saying "good fight, you guys did great this era" is MUCH more likely to kill their drive to continue to screw with you than "haha, you guys lost, gitgud scrub"
