We had this conversation all over the migrants thread on this forum.
https://texags.com/forums/15/topics/3484303/replies/68380879I'm not gonna dig it all up for you/derail this but my thoughts are essentially over there. Catholic Charities has profited enormously (including the leadership pay) from the invasion the Democrats have facilitated, and Pope Marx has said it is a sin to try to stop it. It's all morally disgusting,
as it leads directly and intentionally to the suffering/enslavement in and about our communities of women/children, and our own families.
Manifest destiny is an odd thing to debate/discuss from a religious/philosophical perspective, especially as a contemporaneous matter related to religion today, since it's basically an outdated 19th century concept of American exceptionalism which Democrats particularly today would entirely reject. It's certainly not a christian concept, though as it places a group of people/nation above others (I think one of the core tenets of Christianity is the value of the individual, not groups/classes etc).
I don't think deportation of illegal aliens is remotely related to manifest destiny, but rather an intent to enforce borders, laws, and security are crucial to a functioning state/republican form of government. I dunno, maybe/perhaps there is some tangential link.
