It is what it is

Recently I read a blog. The writer said that saying "it is what it is" is rude. Really? Personally, I use that phrase quite a bit. Sometimes, when things don't make sense and I cannot change it - like waiting a stop light and waiting and waiting watching traffic move without you receiving your left arrow - I can't change it, I can't, without difficulty, leave my lane, honking my horn won't work, so I wait ... it is what it is. Life will move on.
