Alright, so to Clovis, I guess, yeah, the thing I took issue with was using the word "ideology". It's not apt at all. "Ideology" implies some system of belief. I don't think Smith approaches it that way at all. He has a point of view, one that he feels is correct, but it is a point of view that he simply explores with Chasing Amy. And also, I don't think Smith would argue that there are people who are definitely gay or definitely straight, just that the lines are probably not always so rigid, and that bisexuality is probably a heck of a lot more prevalent than people care to admit. I think Smith, especially around Chasing Amy time, would say that in the end orientation is not the issue, it's about who you care about and love, who, individually, attracts you, and who you want to be with.
And even then, that's not the broader theme the film explores. The gay/straight/bi stuff is the lead-in to the much more personal exploration of male insecurities, and in that sense it is totally an exploration, and I don't think the message is voiced like some politician trying to draw an ideological line in the sand. Chasing Amy presents some very real people who connect with each other in some very real ways but all talk like Kevin Smith.
And Sam, the virginity issue. Bleeding and such. That's the hymen breaking, and yeah, that does happen during first intercourse. But not always. Many girls break their hymen through totally innocent means, like riding a bike. Of course there is a physical component to virginity. You either have or have not done it. But most people would argue that the loss of virginity, and more importantly, sex in general is an emotional thing. It's the emotions and feelings that sex can bring about in a person that have a effect, not whether a girl's hymen is broken. Chasing Amy is an exploration of that concept. It takes a really good, complex look at relationships and how sex affects them and the people in them.
