While it's true that Filipinos often enjoy drinking and socializing, there's no evidence to suggest that they're "mild drinkers" in any quantifiable way.
It's important to avoid perpetuating harmful stereotypes, even if they seem to be based on popular belief. Each person, regardless of their nationality, has their own individual relationship with alcohol.
If you are interested in learning more about Filipino culture and drinking practices, I recommend researching reliable sources like academic studies or cultural anthropological articles.
