Effective arguments at AfD in general,  should be positive. Just state the policy and hope the other people will show good sense as well. I try use caution in criticising other's arguments, though sometimes I admit I am less cautious than I should be when I feel really frustrated. And gaining respect for one's opinions there can be b best obtained by contributing to a range of topics, not just those of personal interest, and discussing a range of policy questions, not just WP:NOT. Just some friendly advice from someone who tends to feel the same way you do. ''''''
