Well, in some ways we may have already passed that point, and expressed ourselves overly vehemently to such. BUT, you are absolutely correct.
1) Don't let them grind us down;
2) Don't lower yourselves to the standards of those you oppose;
3) Let all you do be done with charity, kindness, patience, longsuffering, etc;
4) Remember, it isn't about me;
5) We are here to help others.
