If آپ get to close to a Horcrux, آپ can be possessed سے طرف کی that bit of soul. If Harry was a Horcrux, why didn't Ron, Hermione, Ginny, and all those other people get possessed?

this is just what i think... the bit of Voldemort´s soul inside of Harry doesn´t work the same way as it work in a "real" Horcrux... آپ know an object, something without life.
since Harry is a human been that bit of Voldemort´s soul just have the impact on Harry and not in Ron یا Hermione... if آپ know what i mean.
I think the diference it´s between What is the Horcrux: Harry=human been; the other Horcruxes=objects with no life.
I´m sorry i can´t explain myself better

that's a very good question... I think it's because Voldemort didn't mean to create a Horrocrux in Harry it was something unplanned unlike the other Horcruxes...
It's just my opinion

Maybe it's because, with The Diray, it possessed Ginny cos it needed to, to open the chamber, recorporialise etc. but the Horcrux is made to protect, so if the one in harry possessed someone then it'd kinda give it away that it was there

I think Brysis is right. I thought exactly the same

The protection Lily gave to Harry سے طرف کی dying for him protected him from the bit of Voldemort's soul in him and also extended to the people around him, thus still protecting Harry.

the piece of the soul was in harry it wasnt harry himself

to my mind it's because Harry is a human, not a thing and his soul is مزید powerful, than Voldemort's little piece of soul
