That reasoning is shallow. They can't opt out of paying the taxes that support those programs; so what sense does it make opting out of the benefits?
I too have observed an apparent abundance of individuals that decry various forms of social support programs only to change their story when it's suddenly a program that more-obviously hands them support. (There is also a strong argument for social support programs as a method of minimizing the loss to society of productive labor as well as prevention for forcing individuals towards lives of crime so they can put food on the table.)
Not exactly insightful.
Go ahead and point out whatever bad policies you think lead to this outcome, and why you think they should be changed. But calling people hypocrites on a tangential topic (social services) doesn't add anything.
