Wiccan or Mix Mesh?

I have heard alot about Wiccans mix meshing or taking out old traditions and replacing them with made up ones cause they didn't like how the original was.They say they have their own understanding of the Lord and Lady and that the Lord and Lady are fine with it. This has made a lot of the other Wiccans and High Priests and Priestesses very upset since they take the craft, the way of life, the Lord and Lady very seriously. What do you think about this? To be Wiccan or is it ok to be a Mix Mesh? Leave your comments.
