No, dont go straight (lol) into the whole civil liberties thing.





Remember in a Debate- your aim is to SEDUCE the Adjudicators (or audience). So begin on a note that jerks their interest and leads them to believe in the CONCEPT OF HOMOSEXUALS as natural, unstoppable, and a part of some people. THEN go onto marriage and law etc etc.





Example: (off the top of my head)





';Ladies and Gentlemen the motion that I am propsing tonight is that of homosexual marriages in humans. But first I ask, why allow this kind of thing? (Rhetorical questions are good) Its so... and I quote an 18th century.... (whatever make it up, debating is a stage performance) its ';unnatural';. However in the ANIMAL KINGDOM....we have penguins, black swans, seahorses all to some degree show homosexual patterns of behaviour. THIS IS A BIOLOGICAL FACT... apes proving thee MOST homosexual- bisexual or fluid sexual patterns. And so i ask again (then take them back), is this natural? The answer, invaribly is yes.'; (Now you have them half convinced.) And thats your solid grounding. Take it from there. =)How to open my debate on homosexual marriage?
Reference how people once thought interracial marriages were wrong too. After all, this is not any different.





Or you could say something about how we're a secular nation, but there is not a single secular argument against gay marriage (the tax break thing doesn't count because plenty of straight people only marry for tax incentives too, so should we ban all straight marriage?).
There are those that are genetic males that look female, but can only marry a male. She most likely will identify as being female, yet she cannot marry a genetic female unless gay marriage is allowed. She is an XY female.
Civil Rights %26amp; the horrible dicrimination going on.
Fairness and civil rights. Pure %26amp; simple.
