Chances are that if someone shared the beliefs of those organizations listed, they probably already know about the event.
Also, I think it would be more of "Hey honey, did you buy the tickets to the League of the South regional conference?". As I stated earlier, not all of those events are rallies. Some are professional conferenceswhere ita attendees could be people that we all work with everyday. And the usually don't drive a pick-up
Additionally, there a lot of non-confrontational ways to "protest". For example, in an Alabama town, the KKK planned to have a march in the city's downtown area. When they arrived, every downtown business had closed for the day. No one was there but the KKK and the police.
BTW, this information comes from a very informative website called
www.tolerance.org . They track ALL hate groups (regardless of race, sex, class, etc.)
