PSA of the Future... and President Chuck Norris

This is a video that I watched a few weeks ago. I laughed and showed it to anyone who would watch, but other than that did not really think about it. Analyzing this video now, I can't figure out if this is offensive or enlightening. This is a parody of those in today's society who have a tendency to take things to the extreme, but it could also be a disturbing look into what homosexuality means to those who are against homosexuality or very defensive about their own sexuality. I personally would like to think of it as a satirical remark on certain extremists who advocate against anything to do with homosexuality. But I can't help but think about the whole "grain of truth" thing. With all of the advances with gay rights in the past few years, could this be a fear that extremists actually have?
