Okay, so, about the Marlboro man... I have no idea what you're getting at. Cigarette companies have always been trying to sell their products as cool and sexy, so, uh, bad example. And off topic.

Tl;dr, this ad is nothing more than a simple, cute, well intentioned poke at daily family life and how funny it would be to put someone totally opposite from a mother in the kitchen because of the product. That's it! It's not about gays. People are really just looking for something to be upset about.

Whether or not it is innocent irony is beyond the point.  There is blatant homosexuality in the ad.  Homosexuality doesn't have to be men making out or having sexual relations.  It's a lifestyle where two people of the same sex have a relationship of some sort.  This commercial portrays such a relationship.  Sure it's cute, it's funny.  But it's nevertheless homosexual.  I don't think it's malevolent.  I think it's attempting to conform to their idea of the times that we live in.  The UK is probably much more liberal about homosexuals than the US (particularly the Midwest and the South), so it's natural for Heinz to attempt such an ad there.

You don't think the ad was homosexual--I say you're simply wrong.  Now I'm not saying it was overdone and grotesquely inappropriate.  But probably done for a bit of shock value, they want you to remember the ad don't they? 

And I will agree with Gunman, the 21st century sucks.  But a century is what people make it.  That is why we have this battle between worldviews where the frontlines begin in one's own diningroom table.  Fight for what you believe in.  But don't be outraged when people do the same.

You'd owe me a months pay then.  I don't really get my jollies watching smut, and I'd never ask my fiancee for a threesome.  I just don't swing that way.

Also, I'm afraid you don't know what Christ said.  He condemned a whole lot of people and told a whole lot that they were doomed and wouldn't be a part of His kingdom.  So let's not pretend that Christians make up this explicit moral code out of the ether.  Again, I understand your anger.  I cannot imagine having my fiancee murdered for her worldview/identity/whathaveyou.  But don't hate Christians for that.  Hate idiots with no self-control. 

But anyway, your understandable anger notwithstanding, you aren't being particularly engaging or mature in this conversation.  You've been rather accusatory and now vulgar.  If you knew me before this, that'd be one thing.  But I'm a stranger to you and I don't deserve to be talked down to like a dog.  So this conversation is effectively over.

On the other, more melodramatic hand, I think the complaint that consumers had where they had to "explain gay relationships to their kids who didn't understand" is really not the commercial's fault. Obviously the parents have thus fair failed, refused, or have not seen it fit to explain such a relationship to their kids, but if you're letting them watch primetime TV where such an expensive name brand ad would run, they should probably know about these things. The ad itself isn't actually about a gay relationship, and though it is unfortunate that it came across that way more than its intended purpose, it's not to blame for exposing your kids to gay relationships. That's just plain old media.
