Reread the question- it doesn't say "What political group/ideology do you align with?" It actually says ". . .MOST align with," which is asking you which better/most fits your views rather than asking you to chose which you belong too.
On account of your "social construct" comment, I do not feel this way. I have many friends, professors, coworkers, and others that say they identify with the 'right' but are open about having liberal beliefs, for example. One of the users on this site identifies as being more Conservative, but having Liberal beliefs as well. No one is forcing, and no one truly will care if you have some differing opinions than your party that you identify with.
Ehh, I could leave another wall of text explaining why I'm not picking any of these. But wannabepheonix summed it up perfectly, when they pointed out that the group they most align with isn't on the list.
