I have personally seen customs and immigration officers be extremely flippant and calloused with people attempting to navigate the system, and what one agent uncaringly disregarded and ultimately denied, another agent not 20 minutes later a desk or two away had the same exact careless attitude yet approved the paperwork.
For those that get denied due to these poor attitudes and disregard for the human condition, it can lead to acts of desperation, something many have never experienced.
It is odd that in this God (Creator) given world, where less than 300 hundreds years ago, there did not exist any demarcation indicating any type of International Border.
Did you know that even today, there are actual family members of the same Native American tribe separated by this border? Literally blood relatives cut off by the US/MEX border.
Did you know that most Mexicans/Latin American are around 1/3 Native American?
Did you know that in America, you only need 1/4 Native blood to be considered Native?
Did you know that 1/3 is more than 1/4?
Kinda hard to hate on those knocking on their own door isn't?
