Everyone is welcome; especially if it is your first time. This group is made up of diverse people. If you feel yourself to be different then welcome: so are we. New faces with new opinions are much valued.
Debate is a dispassionate attempt to get at the truth of any given issue through reason. An argument is two or more propositions leading to a conclusion that is meant to persuade someone of the truth of any given matter. Persuasion trumps coercion every time. Assent is important but so is dissent. To paraphrase Shakespeare, be true to thine own self and be false to no man.
