a barrier...wow...
he empowered them...empowered them to affect their education...in a postive way
he provided an option to these students that would allow them to remove themselves from his teaching...
and for that...being honest...you know have a reason to hate
The way I seem to view this, is that while it could be said he provided students an option to leave his class if they didn't like his views on homosexuality, as it pertains to his religious views...he's merely a bigot who spoke his mind. Maybe there's a crumb of positive, in that, a gay student who otherwise wouldn't understand why their scores were being affected, (if the teacher were the type to grade based on his emotions/religions rather than purely unbiased scholastic achievement) would have a heads up.
But otherwise, it's a bigot who spoke his mind. "Don't let me know your gay...and we've/you got no problems." While it's still up in the air whether his dogma would have affected grading...he did gay students no great favor with exposing his views.
To me, it's no different than a KKK member saying, "I don't care much for niggers." Yea, he was honest...but it's quite the stretch to view the heads up as a positive.
