See things from the other's perspective

[Badger]

If you're a grown man, and not a whining baby, you should be able to handle this kind of stuff. 

People historically have not responded well to being dispossessed of their culture. It's not an issue of maturity.

When you're culture conflicts with the core values of the country you're living in, its time to re-examine your belief system.

Or perhaps re-examine what truly are the core values of your country, vs. what's just cultural window-dressing.
