wtf?

Ok, my brain has been mush lately. It's that time of the year... you know, when everything is cold and grey and dead and I can't be creative to save my life. (That, and I don't seem to get more than four hours of sleep in a row. I've been mostly relying on catnaps caught between classes.) However, I'm starting to wonder if I'm really losing it, or if (some) people are just morons.

Here's the deal...

Some random guy makes a post on homosexuality. Namely, on the biological aspects of it, and why he thinks that it is only a "defect" and not a natural biological variation. He makes a lot of errors in his reasoning, so I write out a long reply to try and point him in the right direction and show him where he was going wrong.

Ok... no big deal, right?

He then replies... but not with anything on the topic of homosexuality and biology. Rather, he tells me that he didn't even bother to read my reply, but knows that I am outraged at his opinion and that I think that people like him make the world a horrible place.

...

Now I'm just a wee bit confused. See, I outright said at one point in the post that I wasn't mad at all. I just disagreed with his hypothesis. Besides, how would he be able to interpret my emotions if he didn't even read what I wrote?

I ask him that, and try to gently point out that all I did was refute what he had written. You know... it's called debating. One person says something, the next person counters that statement and supports their point of view with evidence. The main problem here being that he wasn't using biological evidence to support himself.

Now he's claiming that he did use biological evidence, and that no current theories on the (possible biological) cause(s) of homosexuality use biological evidence as far as he's concerned.

And that's the situation so far.

Now then, I'd like to ask you all something, and I want you to be honest with me...

Am I just being an idiot and missing some crucial fact? Do I keep missing something here? Has all the snow made my brain short-circut? Has the lack of sleep made me hallucinate the conversation?

(I'm not trying to be cute here. I'm serious. My brain feels fried, and although I've reread my posts and checked over my sources, I feel like I'm missing something.)
