It takes generations for folks too assimulate, lose their ties to a father/mother land from whence their ancestry. Too expect immediate results is, at best, frustrating.
I have respect for culture, we all bring that along the line and pass it on.
What we are really asking for, and expect (in my opinion), is for those who would choose to come among us is to have like desires for theirownselves and their heritage.
These desires should be that where they were did not offer all the personal freedoms and personal determinations needed for them to flourish. This country has, to this point, made these opportunities possible.
It carries with it moral and personal responsibilities. You can if you will but there is failure and personal responsibility for actions involved.
The failures are acceptable with the knowledge that there is more than one opportunity for success. Responsibility is not as common as once but it is intergral and a learning tool for improvement.
If you wish to come to this country and bring with you the hope that you can convert this nation too the type you left, I would think we can ask you to go back.
Blessings
