Fair enough, I honestly understand that.
I think the point though is that people are now making Travis out to be a saint and that he has this almighty moral high ground. Sure, what Ryan said clearly wasn't okay and Travis reacted accordingly, however, it's ludicrous to start calling Travis the "underdog" and that he "doesn't care what people think" when the actual fact is that Travis has alienated the housemates against him. He's constantly yapping, he's not sensitive to anyone's feelings at all.
ALSO let's not forget, that these people also have had a lot of alcohol, and they aren't thinking like they normally would, hence Ryan's sudden move to Travis and Travis's quick retort. I think we need to cut them some slack, and clearly it was water under the bridge the next day as Travis and Ryan were joking around and having a good time.
