Yes - tells me nothing I didn't know, and it still doesn't answer the questions I asked.
It certainly doesn't explain why an unqualified individual (your silence on this matter confirms that this is what you are) should take it upon themself to discourage potential singers from trying to sing.
Nor does it give us any inkling as to how many 'failures' you have encountered to back up your somewhat destructive attitude (your silence on this matter suggests you have never worked with potential singers).
As we used to say in the 60s 'if you're not par of the solution, you're part of the problem'.
