Here's the thing:
I think it's healthy for everyone to try new things, or retry things they don't like from time-to-time.
At the same time:
It's important to try to meet the needs of what people like as best you can, especially in a social setting. For a family with kids, it's important to feed them healthy food and vegetables as much as you can, and at least get them to try new things so they don't look like asshats who refuse to eat green beans because it's icky when they grow up.
Balance, people.
