The da lai lama has reported what he has understood from scriptural sources within buddhism regarding homosexuality. However he is open to evaluating if those beliefs from said scriptual sources are in fact correct. I think he is acknowledging that the prohibition of homosexuality could be simply be native to one culture and time rather than a universal principle.

I don't think the da lai lama has stated that he disagrees with the buddhist scripture but he is open to dialogue to take a closer look at it.
Oh and I don't think homosexuality is considered violence unless it is rape.
