Would I pay to attend? No. But then I do not pay to attend any professional sporting events except for the extremely rare free baseball tickets. They games are ridiculously expensive and the players and owners are abominable. With that in mind, this player’s behavior isn’t in any way surprising. Honor the flag? They can’t honor themselves and others with respectable behavior. They cannot engage in sportsman like conduct.
Perhaps your question should be, were I a typical sports fan would I pay to see this guy? Probably not. Being polite and respectful costs nothing.
That said, I shy from these litmus tests mostly because I do not want them applied to me. People should hire me for a job because I am the best candidate for that job, not for my beliefs.
Looks like you are going to have problem then.
