In Breishit 27:36, Esav complains that Ya'akov outsmarted him twice. He took his birthright and his blessing.
I can somewhat validate Esav's complaint about Ya'akov outsmarting him regarding taking the birthright. In a way, Ya'akov took advantage of Esav's "weakness" at the time.
But, since the birthright had been sold to him (it wasn't exactly "taken"), Ya'akov was the firstborn and entitled to get the blessing of the firstborn. If that's so, how did Ya'akov outsmart him on that part?
In other words, the second action is a consequence of the first. It's a package. If Esav wanted to make a correct point, he prob. should have said something like, "He outsmarted me by taking the birthright, and as a result, he got the blessing."
