Nope not at all.

My fiancee was nearly 300 lbs at one point. She was over 250 when I met her. This is after my previous girlfriend was a model, gymnast and cheerleader. I prefer a fit body of course, but I am not repulsed by fat either.

A bunch of people in my life looked at my sideways for dating her at first, but honestly she's a beautiful and wonderful person who just struggled with unhealthy eating habits. She's been working hard on correcting them recently and is able to do so partly because I am neither positively reinforcing her to be fat the way most fat acceptance movement people do, nor do I bully her or make her feel bad for it the way most normal people do. I've gently encouraged her, and tried to help her make healthier dietary choices combined with regular walks and physical activity. She is about 5 lbs away from being in the normal range for the first time in her adult life now and I suspect she will hit that within a couple of months at the rate she has been going.

This all said, I am also very against the fat acceptance movement in it's current form. It is a SERIOUS health and lifestyle concern and anyone (excepting people with EXCEPTIONALLY stacked muscle mass) over a BMI of about 30, should make it their primary goal to get it down and should aim to be below 25 or so. It is not ok to over-compensate and tell these people that it's completely OK. No it's not. It's a serious issue.
