I saw this on Twitter. Someone posted it (and I'm not saying who because I'm not attacking the person for posting it. My issue is with the picture's message so it's irrelevant who the picture came from.) in their time line and given the link, I assume they picked it up off Tumblr.
I think that picture is ridiculous. Not because I'm a southern girl from Texas who finds stuff like that ridiculous but just because it's stupid. I get the point. It's essentially meant to point out that gays being able to marry (I support gay marriage, btw) won't ruin the sanctity of marriage any more than anyone else already has or will. "Gays will ruin the sanctity of marriage but these hillybilly clowns aren't ruining it by doing what they do and looking how they look? Scoff scoff scoff!"
The pictures are of people on their wedding days. Ideally, most of you wouldn't find the ways they're celebrating their big day particularly appealing. Who cares? It's not your day. If someone wants to do a keg stand at their wedding reception, who gives a shit? It's not any worse than someone downing a whole bottle of champagne or win and as long as they're happy and having fun, again, who gives a shit?
So they have Twinkies, Ding Dongs and other cheap snack cakes out for consumption. Not everyone can afford fancy or expensive stuff. Not everyone cares for that kind of stuff either. So what if they got 10 boxes of Twinkies and then put them out for the reception? There's nothing wrong with that if it's what they could afford or what they wanted.
So what if the bride and groom are getting married in camouflage stuff? Or red? Or plaid and jeans? If that's what they can afford, go for it. If that's what they want and what they're happy with, go for it.
There is no rule that says a wedding has to be white dress, classy tux, pretty colors, champagne, wine, pretty cake, blah blah blah. Not everyone can afford the cliche fairy tale movie and guess what? Not everyone wants that either. There is no rule that says how you have to get married, how you have to look doing it, what you have to serve, how to plan out your reception, etc.
I find it funny that people who are trying to preach tolerance and acceptance of one thing do it by bashing or poking fun of something else for whatever reason. Be it they think it's tacky, wrong, ridiculous, etc. If you want to preach and rant on about tolerance and acceptance, go for it but don't do it by making a mockery out of something else. You're doing the exact thing you're trying to stand up for with crap like this.
