See, now this is the sort of thing that leads to more enemies than friends. People should strive to avoid having enemies. Granted, sometimes it can't be avoided no matter what (see my Crazy Ex-Neighbor) but for the most part, friends are good and enemies are bad.
Now, Eric was just making an observation and/or giving you some stern advice. Yes, this is the Fights Go Here thread, but it shouldn't be abused just to trash talk someone who made you feel bad. People will make you feel bad all your life. Either to intentionally hurt you or to help you in some sort of way. If a person makes one hurtful comment towards you, you should talk about it rather than declaring the person an enemy and going off on some sort of rampage against them.
If you were wearing plaid pants with a polka dotted shirt, I would certainly tell you to change your clothes in the name of good taste. This might hurt your feelings, but it doesn't mean I am instantly an enemy. It just means I am trying to help you, even if it means hurting your feelings.
Now if I killed your ninja mentor and bragged about it to my cadre of mutant porcupine warriors, then you would have reason to claim me as an enemy.
Learn the difference. It could mean the difference between life and death.
