bicultural would be a better tag than bilingual. The issue at hand doesn't seem to intersect much with language use or acquisition.

@Arturino oh! Switch back to speaking English all the time. Exposure is everything. Us Americans don't know how to raise bilinguals but we know how to kill a language-- just stop speaking it. I count 6+ lost languages in my family. (I admit, it would be a chore to have to grow up knowing that many)

The math for lingua francas and community languages are different. If you know a community language, you have a community that will take you in in times of disaster, when you need a business partner, etc. (Think Yiddish in New York), if you know English, people merely understand you, you aren't necessarily a member of a club. I agree, in the USA, 100s of hrs spent in High School, failing to even learn Spanish is a waste of time. But toddlers pick up languages effortlessly when the parents speak it. Teenagers & Adults, way different costs.

The word "force" is a red flag, a sneer word. People react to it like you are suggesting beating your children with iron rods and can't focus on anything else after that.
