You'd probably get laughed at.
It wouldn't be because people thought seafood was dumb. It wouldn't be because you looked funny, or were female, or played poorly that day. It would be because you misunderstood why the team went to Bob's week after week. The team doesn't go to Bob's because they've got a taste for pizza, they go to Bob's because they want a comfortable routine, shared experiences, and customs to uniquely identify their group.
The suggestion of giving those comforts up because you had a taste for fish sticks instead of pepperoni would be funny to the people who really appreciate them.
And so it goes with baseball on the TV.
It's a simple fact that usually in groups the majority rules. The majority wanted to watch baseball, not Friends.
No. OP wanted to change the channel away from THE established channel.
Had OP been a male, and a woman changed the channel back to baseball, the situation would have been the same.
And not only once -- the single event of her requesting a switch to the different show was repeatedly ridiculed, as if this was a completely outrageous suggestion. This would have been quite okay if she asked "could we watch Friends today instead" and the other team members looked at each other and simply responded "Eh, we'd all really like to watch this game".
you may be thinking about a 'Republic', in which the rights of the minority are protected, but THIS is democracy in ACTION.
To put it as clearly and simply as possible, as if we were examining the results of a double-blind clinical trial:
OP attempts to change the channel. OP is loudly ridiculed in an unpleasant way.
Rando teammate changes the channel. Everyone thinks it's a really funny joke.
What changed? Just the OP. It's pretty obvious the team doesn't like her the way it likes the rest of its members. Is this necessarily an example of sexism, like the seat-belt incident that OP also references? Not necessarily, but it's certainly quite alienating.
Also, while I'm generally sympathetic to the idea that there is a hierarchy of things that are better and things that are worse, how impactful an event is, is ultimately subjective and often not under any conscious control. The time I was mugged in San Francisco honestly made much less of an impression than the time my coworker said he hated all of us and refused to go out for lunch.
