I feel like hating him for being silly totally misses the point. Hagrid is one of the kindest, gentlest, most loving souls in the story. He gives unconditional love not only to Harry but to all innocent things, which includes animals and magical creatures. He sees the good and the vulnerability in even the most ferocious of creatures. Therefore, it just pains me to see him get hated on. He has his flaws, surely, but if he didn't, he would be a boring, one-note character. And his flaws add to his goodness; he makes mistakes because he's too trusting, which only adds to his character of unconditional affection and love.

I just love Hagrid so much. He is so sweet and strangely innocent. Hurting him is like hurting a defenseless puppy lol.
