Hey Siggi56!
I'm not allowed to say here what I think of the 'personage' who told you it was an insult to your audience to cry.
First off you are a musician - a purveyor of emotion through the medium of sound. If you don't try your own product how's anyone else supposed to take your word for it? If you don't feel it how can you convey it?
Come to think of it that's it!
I cry or get choked up often when I play. Sometimes it's what the song means to me; sometimes it's the song itself; sometimes, if there's a song that I've been wanting to learn for years (sometimes decades), cracking it can crack me - perhaps that is arrogant of me or prideful at least, don't know haven't thought about it, not gonna bother, got better things to do!
Songs which feature artits crying or emotional voice cracks include:
Michael Jackson - She's out of My Life (one of his best)
Sinead O'Conner - Nothing Compares to You
Is there anyone who can listen to either Elgar's Nimrod from the Enigma Variations or Kate Bush's This Woman's Work without getting a lump in the throat? (If you don't it's best you say nothing! Likewise if you Beavis and Butthead -out at the mention of the word 'Nimrod')
Just now while trying to find the name of the above mentioned Kate Bush song I digressed into another of hers all of which I could remember was
"...all they wanted
was a sound that could kill someone
from a distance.." ( less than one line, Per)
and when I saw those words looking back at me in the Google search window I started to well up. Perhaps it was the perversion of everything that I hold sacred - a child's laugh, my dog barking 'cause he's pleased to see me, hearing the words 'I love you' or a song from the heart, etc is what sound should be about!!!
Don't fight it but use it - it will use you so get used to a symbiotic relationship.
If what siggi56 or I have written embarrases you or you think that it's wet, I just have to say - "This is Chordie a site for musicians, are you sure you're in the right place?"
Good on yer siggi56!
