If 당신 had a Demi hater right in front of you, what would 당신 say to them to convince them to stop saying mean things about her?

I personally wouldn't say anything unless they were a friend.

If they're a friend, let them know 당신 like her 음악 and think she's an amazing person and 당신 would appreciate if they wouldn't say hurtful things because they don't know her.

If it's not a person 당신 care about then don't waste your time. There will always be haters out there and 당신 can't control what people say. Just focus on the positive and the people who do think Demi is amazing and talented.

I'd be all "You'd better stop talking shit about my main girl Demi, Fool."

i would say STOP thats mean because if some one said something meen 2 u u wouldnt lik it!!!!!!

Um.. there is something wrong in the question... Not just because he/she hated her means she/he says mean things about her..
so my answer is...
"Think about this, dear Demi Hater... Do U know her? Do 당신 know yourself? 당신 may found that she has a similar personality like yours so if 당신 are going to say mean things about someone, think first about who 당신 are!"

Id say " Dont talk about Demi like that 또는 u'll be wishing 당신 didn't missy/mister "

I would back DEMI up and tell that Demi hater that she is pretty, she has a Really GREAT VOICE, she's a GREAT singer, she has a GOOD career, she became SOMETHING BIGGER than 당신 would ever be if 당신 wasn't such a BIG HATER of her. Instead of HATING her LEARN TO 사랑 her, get to know her listen to her songs, watch her performance live, then 당신 would become something bigger like her & learn to 사랑 her.
I am a BIG 팬 I 사랑 당신 DEMI💟 . 더 많이 than anyone so much 당신 are MY IDOLE!!! I 사랑 당신 SO MUCH THAT I WILL BACK U UP IF I EVER SEE A DEMI HATER TALKING BULL**** ABOUT U. AND IF I EVER SEE A DEMI HATER TALKING SH** ABOUT U I WILL BE SO MAD😡 ! I WILL DO EVERYTHING AND ANYTHING JUST FOR YOU!! 당신 are the person I 사랑 더 많이 than anything in my life.
