You have too much respect for the clowns that get elected into the office. And you have too much respect for the office; it makes you vulnerable.
It's not about respecting the clowns, it's about paying respect for the traditions and culture if the USA.
Vulnerable? Not even close. It's about having dignitas, gravitas and decorum.
Would you show up for a wedding or go into church in shorts and a T-shirt? Show at least that minimum level of respect when you visit the White House.
