Not everyone who has a differing view from the common consensus is a "paid propaganda spreader" and a differing view does not make someone any less worthy of engaging or taking seriously.
I would not classify the OP's post as unsubstantial. He makes an effort to type fully formed opinions and many of his comments are backed by citations. If you want to see an example of objectively unsubstantive posts, please see . You will only find one-liners and unsubstantiated, inflammatory statements.
By the way, your comment also break HN's rules on accusing others of astroturfing:
