Look its like this.

You start singing, performing or whatever and people criicise you.

Someone is going to say you're crap. If you pursue performing for a living - sometimes whole rooms full of people will decide you're crap.

it goes with the territory.

Every performer puts up with it, or gets out. Every one: Elvis, Sinatra, Pavarotti, Carthy, Dick Miles, Ron Kavana.......

Whenever two or more gigging musicians get together they have a drink and a curry and tell war stories. And they criticise back. So you criticise away......

Because in a way, you're doing us a favour....adding to the fund of folk tales amongst musicians.   stuff like...

'I understand what you're sayin', its an acoustical guitar, BUT DO YOU DO ANY SHADOWS NUMBERS?'
