can you be called out on a walk

Mcrowder,
I don't understand your response.
There was NO ruling by the umpire.
What rule are you protesting - the walk the umpire issued?
Not gonna happen.
There is no protest here.
Even if the umpire decides to toss the guy for UC, it will be after the game winning run walks in anyway.

To answer the post, the loss is valid.
The umpire could toss the B/R for Unsportsmanlike Conduct, but that comes after the walk and the winning run scores. Unfortunately this idiot gets to let the winning run score either way, but I am with gsf23.
I would like to stick around and watch this guys teammates when they see HIS actions cost them the game.
But that is not to be in this instance.
Too bad though.
