Duncan was very unhappy with his experience and his treatment as a CFAR employee and his interactions with Anna Salamon in particular, including being pressured into doing things against his better judgment. If he prefers not to go into details, I'll respect his wishes, but after following him for a while I've got somewhat of a handle on what happened.
This is definitely a warning shot, but it's not quite there yet. Being able to infect and kill cells in a lab isn't necessarily enough for a virus survive "in the wild"; it has to be able to survive environmental conditions and immune responses, reproduce itself inside the cells, and then be transmitted to new hosts. Still, this could definitely end up being pretty scary in a hurry.
Weight is such an extreme determinative factor in combat sports that an untrained 250-pound couch potato could walk into any boxing gym and absolutely demolish a 100-pound opponent with decades of training.
You later link to a video of an early UFC match in which a much heavier person is beaten by a much lighter person when the lighter person kicks him in the face. But yes, that doesn't happen very often, especially when both are fighting in the same style.

Dr. Seuss is also generally fun for adults to read to children. (The illustrations do a tremendous amount of work in that regard.)
I also noticed the similarity!
Has he read Green Eggs and Ham?
Possibly pointless nitpick:
When it comes to things like lesbian firefighters, beware base rates! There are a lot more heterosexual women than homosexual women, so it can still be true that, even though the percentage of lesbians who become firefighters is greater than the percentage of straight women who become firefighters, most women that are firefighters are not lesbians.
