I am entitled to give my feedback to anybody I think.
Feedback is not meant as asking somebody to change, it's there to tell how you felt.
If the addressed person agrees/disagrees doesn't matter. I believe the world gets better if everybody is allowed to voice their opinion
Yep, I said feedback is most likely fine. I said it. I also believe in feedback for a better world (when I said you aren't entitled to anything, that was sloppy phrasing for 'the blog author owes you nothing').
But the way you give feedback matters, and you are not entitled to be a jerk when giving feedback. Now, I don't believe OP wanted to be a jerk. I think vanishingly few people actually want to be mean. But I think the world is better off if people take their recipients' feelings in account, because it's nicer.
Another perspective: if giving feedback is indeed your intent, surely you care about the recipient and how your message is received (otherwise you would not bother). Your feedback will likely be more effective if well received, so you definitely want it to be well received. So you definitely want to avoid hurting people's feeling as much as possible (of course, sometimes useful feedback will inevitably hurt, but anything beyond this is harmful to your goal).
Whether your recipient agrees is an orthogonal concept indeed. I'm totally fine with respectful feedback given to me with which I disagree. It's okay to be wrong. (:-D)

Yes, of course! And others are entitled to ignore your feedback, downvote your comment, or say it to your face that your feedback is unwelcome, or flag your comment as they see fit.
