The men were being used by Trump as a prop
The men were on a call from the president, high off of their win, and laughing at a battery of harmless jokes. Then Trump snuk in the mysogenistic one. i think some laughed almost automatically because they that was what they had--so far appropriately--been doing. There was no time to reflect. If there were some--even a majority--who didn't laugh, we wouldn't be hearing their silence.
Statistically there will be some MAGAs on the team. Some will just want to enjoy attention from a president. The anti-Trumper's will behave with respect. None of them initiated insults against the women.
I really think they were being used by Trump as a prop, and he pulled them into his disfunction. No one should have to worry about being put in such a position by a president.
I'm glad some expressed their regret after the incident, and their respect for the women's team. And I have even more admiration for the women for sending that respect right back, understanding the difficult position the men were in.
