In fact, her tomboyishness plus touchy-feely behavior is what prompted Blair to assume that Cindy batted for the other team (i.e. that she was lesbian or bisexual).
Not it that it would've mattered had Cindy or Jo came out as such. I mean, Cousin Geri (Geri Jewel) came out around the same time that Lisa Whelchel (who played Blair Warner) returned to television! XD
