If he were an avowed fornicator, you bet! See, heterosexuals have the good taste to understand that immorality is not something to flaunt in front of children. Those who don't have no business being leaders to children anywhere.
If memory serves James Dale flaunted nothing. He was, by all accounts, a good scout. An Eagle scout, a dedicated and popular assistant scout master who did not bring up his sexual orientation at any time to any member of the troop. He never once harmed or threatened any of the scouts under his supervision. He never once connected his membership in the Boy Scouts with his private life. Never once discussed homosexuaity in any manner with any of the boys. In fact, the only way the leadership of his troop found out about it was when he was quoted in a college newspaper as a member of a gay and lesbian organization. So I fail to see where his actions warranted his dismissal, other than the fact that he was gay, of course. Had he been living quietly in sin with his girlfriend then he would still be a scout leader. If he had been an alcoholic then he would still be a scout leader. If he was divorced or a wife beater then he would still be a scout leader. It doesn't seem quite fair to me.
