You are right. According to your title of your thread and your posts, you are trying to determine the level of rudeness for blowing off a certain type of wedding.
You keep arguing that it is "less rude" to blow off a wedding after you have confirmed you are attending if:
- You don't approve of their method of invites
- They have not spent $0.44 for postage of said invitation
- They don't have a sit down dinner
- The venue didn't cost as much to rent as say, a ranch
- There is no alcohol being served
- It is light appetizers, not even heavy appetizers
In other words, per your arguments in this thread, the less somebody has spent on their wedding, the
more ok it is to blow it off.
You keep saying it is not about the money spent on the wedding, yet every argument you pose that it is "less rude" otherwise known as "more ok" to blow off a wedding, involves the amount of money the bridal couple has spent.
As far as I was taught, there are no levels of rudeness. It is either rude to blow off somebody or it is not. It doesn't matter how informal, how much money is spent or whether I agree with the way they did something or not.
But then, we must have been raised differently. Maybe it is because I am an old fuddy-duddy that has been on this planet for over half a century that I was raised that there are never degrees of rudeness. You are either rude or you are not.
