however, i have been on the receiving end of these campaigns and they are designed to keep at a person until they get such a reaction.
do not believe that this was a random action. this person probably emailed many military members until he/she found one that would take the bait, then continued to hit until enough was written to be posted and rile up the public. hitting the military is one of the agendas of the gay community.
if you are openly gay, the military does not want you. there are some very good reasons for that. "don't ask, don't tell" is a more than generous policy.
