I had frog legs once. It was fine. Like a lame chicken wing. I didn't hate it, but I couldn't see bothering with it again.
Beer, though, it's so all over the place flavor wise these days, I don't think a single sampling really tells you if you like "beer" or not. Maybe you don't like hops. Or a specific hop. Maybe a milkshake stout would be your jam. Who knows.
That said, I don't care if people don't like beer, but I do find the challenge of "I don't like beer" fun.
