I also think it's a great idea. I've seen several people on other boards calling it a "smokescreen" and what not. Comparing it to the tobacco industry running anti-smoking ads.
Now, I'm not going to debate whether or not those arguments have merit.
Ultimately, if in fact studios commit to this, implement this campaign and actually do what it is HDK has suggested... it could very well make a beneficial impact on the gay community.
A video such as that, distributed through those means and freely available to a public that's demonstrated an interest in sexual activity, would be a good thing. I hope other studios recognize, acknowledge and act on that - as opposed to being motivated by politics or their feelings towards who initiated the idea.
