It's strange that you say "why on earth would I change my party affiliation based on the actions of two members" as if those two members weren't the two highest elected members of the state party. It's like if the CEO and Chairman of the board of a corporation were embezzling funds and someone replied "Why would I change my opinion of a company based on two random employees?"

I think you did that because it's pretty obvious why someone might sour on an organization whose highest leaders continued in a pattern of bad behavior. In fact, quite the opposite of your claim here, I think it would be common sense to change your opinion on an organization based on a pattern of misbehavior by its top leaders.

The reality of modern American politics, though, as I think you demonstrate as do most people, is that Negative Partisanship is the only factor at all that matters. The people on "your team" can do anything at all, because "the other team" is worse. This is the sentiment that drives all American politics at the state and federal level.
