I'm glad that you are willing to stand up and proudly admit your enthusiasm. To me, that's a mark of being a true fan
While I readily admit to not being a Rachael Ray fan, I understand there are tons of people out there who adore her. One of my best friends is a fan. She buys her magazine and watches her shows and we get along just fine.
As others have said, it would be a boring place if we all liked the same thing.
When I first got my DirecTV service and started watching Food Network, I watched 30 Minute Meals. What got me not to like her, and of course this my opinion, was it quiet obvious that I know more about cooking than she did because she did things that were wrong. I didn't know at the time she was not trained in the culinary arts. So for me, I'm looking for people who can teach cooking rather than give me a recipe. But that's just me.
My favorite FN personality is Alton Brown and I know there are people out there who find him annoying. But, I stick to my guns when people say bad/mean things about him. So, keep up your support for Rachael no matter what other people say or tell you because if you like her its no one else's business!
