"Alex" really needs to get over this. It happened in 1995. You guys were what 19, 20, 21? If it happened last week or even last year, I would understand his anger, but 8 years ago.

You can't please all of the people all of the time. You have to be true to yourself and your values. You were a young man who tried to resolve the problems of your fraternity as best as you can and were successful. BTW, "Alex" couldn't be president if he wasn't enrolled in school.
Ignore the e-mail.
