"Not being able to afford a wedding hasn't stopped straight couples from getting married...why should it stop gay couples?"
You do understand that in order to get married, a license has to be purchased? Maybe in whatever state you live in, unemployment meets all your needs. In NY, the maximum is $400 per week, which doesn't get you very far.
And yes, not being able to afford the wedding has stopped straight couples from getting married. Many have started living together without the formality.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
