Checking out the lay of the place for the upcoming attack was a tactical move, and like Daniel states, even if he was a homosexual, so what?
Islam is an ideology of duality, completely contradictory verses, dual rulings and edicts doesn’t matter. Cognitive dissonance is an Islamic prerequisite.
WHY IT DOESN’T MATTER IF OMAR MATEEN WAS GAY
There are various reports that Omar Mateen, the Muslim terrorist who carried out the attack in Orlando, had visited a gay bar and used a gay dating app. Assuming this is true, does it matter?
Muslim terrorists often pick targets that they know. The San Bernardino Muslim terrorists hit their husband’s workplace. It would be logical for Omar to target a place that he was familiar with.
Our current mindset is that life is a binary proposition and if you are a Muslim who hates gays, then you can’t possibly be gay. But the regional view has a more nuanced view of homosexuality, witness the “dancing boys” of Afghanistan, where a Muslim man might engage in gay activities without being gay.
