It's about whether saturated fat is or is not distinguishably unhealthier than other sources of fat, once other factors (most importantly, obesity) are controlled for. The evidence from properly constructed studies suggest that it is.

For my own self, I know that red meat and saturated fat increase my risk of heart disease. But they are delicious, so I eat them -- in moderation. And I monitor and control other risk factors such as exercise and blood pressure.
