Brutalist architecture is meant for simplicity and showcasing the materials. Putting stuff on it is a jarring visual clash that fucks up the beauty of the building and the skyline. The flag is bad enough, the quote is just too much and has been an eyesore on a really unique and interesting piece of architecture.

Oh yeah and there's also the fact that Reagan and his ilk are basically responsible for the shitty state of the country today by virtue of killing regulations that enabled megacorps to run roughshod, propping up Saddam Hussein, creating Al Qaeda, ensuring cycles of violence in Central America, propagating hate against LGBTQ people, and for the cherry on top, swelled the defense budget to astronomically high levels based on literal lies, which still continues to this day at the expense of any kind of health care, education, public health and sanitation, etc.

If you're going to put stuff on a perfectly good building in a show of demonstrative post-9/11 patriotism, at least pick something from a president that's not a complete destructive force against the country.
