I view some of the ideals in Christianity wrong, but that doesn't mean he's automatically a Christian due to a hate crime. There's other religions with similar ideals.
It's South Florida, that's how I know. Also, there's this:
"The 25-year-old victim said the child chased her down the street shortly after midnight in the area of
Church Street and Rio Grande Avenue, which is near the Citrus Bowl, while firing shots and
yelling threats and homophobic slurs at her, investigators said.
Seven shots were fired. The boy lives with his grandmother, Josephine Felder"
Not all homophobes are Christian.
