That aside, I simultaneously hold several thoughts about this.
The first is: The TSA probably doesn't need to exist at all in its current form; I'm not aware of any evidence they actually do anything to stop actual threats.
The second is: I have sympathy for the folks who work there, who probably are in it mostly to have a stable and non-controversial government job. I'm sure they're going through it, for political reasons that are not their fault.
The third is: There is zero political incentive for either side to cave on this, that I can see, and as somebody who is generally opposed to the behavior of ICE, I think we as the American public will just have to eat it until they are reined in. I'm including myself in that; this has messed with my travel plans and will continue to do so.
But if I were on the other side of the issue, I think I'd hold the exact same opinion: There is no incentive not to continue the shutdown.
Apparently Sea-Tac has a very low TSA absentee rate:
