Most of the time, a kiss is just a kiss in the stands at Seattle Mariners games. The crowd hardly even pays attention when fans smooch.

But then last week, a lesbian complained that an usher at Safeco Field asked her to stop kissing her date because it was making another fan uncomfortable.

The incident has exploded on local TV, on talk radio and in the blogosphere and has touched off a debate over public displays of affection in generally gay-friendly Seattle.
