“You are a walking talking example of a miserable old man who wants to make excuses for other people, while shitting on those who want to make the most of their life and find fulfillment, because you probably didn’t find it in your own life”
In my opinion, comments like this will only harm you in the long-run. If you want to be a successful entrepreneur, taking great care in your response to criticism — regardless of how constructive it is — is key. Not many people will be interested in pursuing business with you when they see reactionary blog posts like this out in the open. Professionalism and kindness are very, very important. Perhaps this is the persona you would like to portray to your readers and the rest of the world wide web. Regardless of intent, I think it is important to at least reevaluate how you want to brand yourself.
