Not only is it weak disabling comments, it is typical leftist ideology, "Only my opinion matters, because I am correct on the issue, there will be no debate, only agreement".
Leftists get in circle jerks of agreement with each other "Yes, I agree. Oh, wholeheartedly I agree also. Yes yes, you are SO correct!!".
But DISAGREE with them? That just wont do. To them a negative comment or disagreement is like leaving a flaming pile of dog poo on thier porch and so they just disable the ability to let it happen.
