I think you are still interpreting this from the wrong angle.

I certainly would. Actually, I did. My confidence had already taken hits before from nicer private feedback I got before.
I also disagree that I should dismiss everything that an asshole is saying just because they're an asshole, even if they are right. I take what is right, improve my text and forget about them being an asshole.
I once got the advice that my target group should be the ones deciding if the quality level of my work is good enough, not myself. If they see value in what I do, I'm good. I still will strive to improve further, but there is no reason to stop, as long as people like my work.
Therefore, focus on checking that your regular readers are enjoying what you write, instead of focusing too much on actual or perceived weaknesses.
