I can't imagine if the suspect was a conservative Christian that most on this board would stand for people blaming all of Christianity for the stabbing. Islam is very conservative on homosexuality, but that doesn't mean all Muslims go around stabbing gay people. With all the anti-Muslim sentiment that exists a lot of Muslims try to keep a low profile and live as quietly as possible to avoid harm.
Yup, though the anti-Muslim is often grounded in other reasons than homophobia among Muslims. Anyway, an embarrassing and pathetic crime that needs to be brought to justice. Regardless of his age; at 17 you should know that killing is wrong.
