Even if I'm buddhist, I won't goto protest for such kind of buddhist paintings because everybody know buddha didn't kill anybody. So buddhists don't have to prove it again. Regarding sex, he'd many sex while he were inside palace. So, i'll take second painting as portrait of his early life before enlightenment. I think that naked paintings of gods are okey. There's nothing wrong in that imagination. But something is definitely wrong in portraying these gods having sex with animals. If gods're Homo sapiens, this shows that they're same like us. But i don't think they ever had sex with animals.
