Homosexuality & Bible debate part Duex

Original Post for context: http://www.reddit.com/r/atheism/comments/u0ita/1st_post_looking_for_feedback/

So, apparently the gentleman I have been talking to is some sort of pastor or youth leader or something along those lines. He responded with 4 very long comments (all of them with very bad information IMHO) and included 2 links to sermons he did that are listed in iTunes. I have not listened to them, nor do I plan on it. I decided to respond mostly to the topic at hand, with plans to return to and tear apart the rest of his arguments at a later date. I have to admit it is very hard when someone admits taking information from apologetics websites to take them seriously, but I tried.

He did fail to get my sarcastic humor in my previous dragon and unicorn mention, but his rebuttal to that made those mythical creatures seem normal. And his examples for proof of the existence of Jesus... Do I really need to point out the obvious flaw in that argument?

Anyway, here are links to the conversation if you are interested. They are very long:

Any feedback would be wonderful. I am more looking to make sure I don't have bad information in my responses. Any way to make my argument stronger, and make sure the info I have is correct.
