Let's look at other examples with different people.
Everybody kind of understands that nick fuentes is gay. There are a lot of reasons why people would come to that conclusion, but the pertinent one here would be how many times we've got video/audio records of him saying or doing gay stuff. And sure, irony is a part of that guy's brand, but did people think he was *more* or *less* gay when his response was to say "it's just irony, it's just comedy" and continue to say and do gay stuff?
Mcnabb could very well be just doing bait, just like nick could very well be just doing ironic faux-homoeroticism, but when he does it that much, continues to do it, and everything he says on the topic is in line with it, it's reasonable to take it as a revealed preference
