I really torn on this. (No, not on shooting up a synagogue or other place of worship).
I'm pretty anti-illegal immigrant. However, there are people fleeing from places where if they would have stayed they would have been killed. (Iraq Christians immediately jump to mind.) Plus the people you jump through all the stupid hoops to get either a green card and/or become citizens. So those folks, true refugees and immigrants I joyfully welcome with open arms.
However, there are many people that claim they are refugee's, like the hoard(s)/caravan(s)) heading north from Honduras/Guatemala. Last I checked there's no civil war there. The government isn't rounding up people, any people, and putting them in camps or executing them outright. So, sorry. Not Refugees. You're only coming here for the money. The fact that Mexico has offered to take you in and give you food, shelter, clothing, and jobs; yet you insist on pushing until you get the US border, just proves that fact.
But I also get where these synagogues are coming from. Years of persecution, fleeing from war, governments, regimes, even just groups of civilians that want you dead, and pogroms. I get it. We've been on the receiving end of all that. The SS Saint Louis is always in the back of our minds. That we can't do, what was done to us, we HAVE TO provide refuge. All the synagogues around here in involved with resettling and aiding refugees. Whether the congregation is Reform, Conservative or Orthodox, they all are involved. Yes, we are supposed to do good works and make the world better. I get it. I think we just need to tighten up the definition of "refugee".
