I'm not interested in delving into pedantry, so I'll stop after this. My intuitive understanding of this phrase is that strong or weak opinions are generally a measure of magnitude more than stability, while strongly or weakly held opinions are a matter of stability rather than magnitude. Someone might have a milder opinion of something, like "Pepperoni pizza is fine" vs. a stronger stance, such as "Pepperoni pizza is the BEST pizza." How easily that opinion is changed does not necessarily correlate. Perhaps the person who thinks pepperoni pizza is the best has never tried salami pizza and will be an instant convert. Maybe they're the worlds BIGGEST pepperoni fan. Maybe the person with the weaker opinion on pepperoni might be very very unlikely to change it because they don't care enough about pizza in general to consider it much. Maybe they love pizza, but are one bite of pepperoni pizza away from saying "bleh, hand me a slice of mushroom."
