As long as you don't hate on the dude by stopping the hot water in the basement to try to prevent any bathtubs from being filled with hot water, Tupac and three women - it's ok. Because he could not care less about what you think.
It's just the way he was. Dude was VERY sensitive, (like I am). So we show emotions all the time, good or bad.
But no one likes to be in a bad mood, or be fake. So him being himself can easily be categorized as gay because he wasn't afraid of what people thought of him. He was a person of genuine heart and he was very peaceful and loving. It's why his poetry and acting was so great too....b/c his sensitivity allowed him to be very happy or angry.
