Is it possible heath ledger died because he played a gay guy in a movie?

well according to the reports (years back, Y are we still dwelling???) he mixed too many tails of prescription aand possibly illicit drugs, and he was in the middle of filming the Dark Knight Friend so your "agenda" has flailed to bring it about due to Brokeback mountain, egads....he died as a result of personal free will/bad choices or decisions. Case closed.
