You'd think sex workers would have learned better than anybody that ejecting someone from your society because they have moral opinions you disagree with is a bad idea
But no
To be fair, sex workers are probably not the brightest bunch on average. They don't need to be. Not that intelligence is all its cracked up to be ether.
Logically on average I think it might. There are no barriers other than being physical and mentally able to perform the required deed. Its a job, at its lowest point, 'anyone' can perform. I think that means it's going to dip towards the lower range of intelligence.
