Well that's a stupid take too. I do my job and my employer pays me. That money is now mine. What I do with that money within the bonds of the law is no one's fucking business. That goes for elected officials too. I don't care if the an official spends every spare dime of his money getting drunk on nights and weekends if he's still competently doing his job. Idk if he is competently doing his job, but I don't think this necessarily indicates that he's not either. And if getting drunk once is enough to indicate someone shouldn't hold office, that's bad news for nearly every American politician.
If the line is drawn at the door of any goverment building especially one that's isn't currently open and doing business, that's strange too. They're not hollowed ground or holy sites. They're administrative buildings. People working there are people. They piss and shit in those buildings. They microwave fish. They spread their shitty fucking colds. If the very idea that someone may have had consenting sex in one of the rooms disturbs you, I would suggest you not go into any building ever. Someone has almost certainly been fucking there at some point.
