> Usually I clear immigration in Ireland (one of the few places you can do the immigration before you leave), and those folks are always much more pleasant.

FYI: It's not just Ireland that let's you clear US-immigration before departure: https://en.wikipedia.org/wiki/United_States_border_precleara...

I've been going through Dublin myself for years, and I can highly recommend it: In worst case, you'll be told to leave the terminal, but you won't go into a holding cell - and yes, officers there are much more friendly than their counterparts in the US (I guess they are all infected by the Irish hospitality).

I've got some bad news for you, there's a bill being debated in Canada about giving US officials the discretion to hold or detain travellers at pre-clearance centres:

https://openparliament.ca/bills/42-1/C-23/

If it passes in Canada, it's only a matter of time before it happens in Ireland (or you lose the pre-clearance option).
