Debate threads are places where shippers from opposing sides argue it out over the opinions of a ship and/the merits of the ship itself. But it takes two to debate. If someone isn't debating you in the debate thread, post your thoughts without dragging them into it (ie quoting them from safe haven love/hate threads). If someone is debating you in the thread however then you can bring over whatever they've said to debate them about the topic if it pertains to the evidence/reasoning you provide that oppose their opinions about the ship.
