I empathize with the people who have no other choice but to work for the TSA, that is a shitty place to be in life, but I reserve the right to at the same time criticize their job and them for doing it.

The extension of your argument (and I have seen this said here many times before) is basically that we should not criticize Rhinoceros hunters because said hunters may just be trying to etch out a place for themselves and their starving family in this world. Yeah, it would suck to be in that position, but hunting Rhinos is still reprehensible. I understand why they do it, but I cannot condone it and I cannot withhold my criticism.
