When you submit a reason to disagree you are submitting a new Thesis: that the original thesis had one of the following logical fallacies:

1. Fallacy of Accident or Sweeping Generalization
2. Converse Fallacy of Accident or Hasty Generalization
3. Irrelevant Conclusion
4. Affirming the Consequent
5. Denying the antecedent
6. Begging the question
7. Fallacy of False Cause
8. Fallacy of many questions
9. Straw man

Once you do this people will be able to vote if they agree or disagree, post reasons to agree and disagree, etc.
