My initial reaction was anger. His comment felt hurtful because despite what he really thinks he should at least have been a bit more considerate to the show’s (and his success in turn) even if a large majority of it is from Sterek fans.
I understand that he puts his heart and soul into the show and based on 99.9% of what I have seen about him, he seems like a really amazing guy. Putting myself in his shoes, it must be hard to know that there are fans that only watch because of Sterek; it might make him feel like the actual parts of the show that he is a part of are not as important.
I don’t fans should stop watching and I don’t think Posey should be getting hate for his comment. He could have phrased it better, yes, but he is entitled to his opinion…even if I, or you, disagree. I enjoy the show with and without Sterek moments and so long as the show itself is written well, I will keep watching.
