Having lived in Chicago all these many years, I know Oak Park fairly well. It's right down there with the People's Republic of Evanston, IMHO.
Oak Park is the suburb where the PTO's tried to revise the charters of the Cub Scout Packs they sponsored to put an anti-homosexual-disrimination statement in them. Mind you, Cub Scouts are from 1st to 5th grade. I don't know if the PTO's were worried about gay 5th graders or if this referred to the leaders. The Council (Des Plaines Valley Council in La Grange) refused to sign off, National backed them up (of course), and the PTO's refused to re-charter and let their Packs lapse. Most of the kids joined other Packs.
It's worth noting, by the way, that the BSA doesn't discriminate against all homosexuals; just those who are "avowed", by which they mean those who are open about their sexual orientation in public (e.g, around the kids). The concept that their sexual orientation is none of the kids' concern apparently escapes them.
Funny - Evanston and Oak Park have the highest percentages of gay residents in all of Illinois. Whoopee!!!!!!!!!
I know both fairly well, but think that Hyde Park tops either one as a bastion of socialism.
