I meant the actual ads themselves, not particularly the products. The average porn banner ad is an assault on the eyes, even if you're in the market for porn. I don't know if this is inherent to porn or just because it's an impulse-buy information good which is usually advertises through multiple levels of affiliate. Most firearms or knife ads are the name of the product and maybe a static shot of the product. e.g. http://www.blackfriday.fm/bf_image/big/2011/37266_1321045669...

It's a fair argument that porn is pure free speech and thus should be less regulated than guns, or that it's morally superior (although I'd say sex is morally superior to violence; porn is in some most cases morally inferior to sex)
