Aren't walls useless and racist?

so then why is a concrete wall being built around the White House?

White House Erects Mysterious New Concrete Wall Without Explanation.

The Biden White House is erecting a concrete wall in front of the building, with no apparent explanation for the security measure.

Amidst the construction of the wall, live video feeds of the building were also reportedly killed. While the construction of security barriers can sometimes occur ahead of foreign heads of state visiting the U.S., no events have been publicly announced or scheduled.

It looks like #SharterJoe has been to the Nancy Pelousy School of Domestic Terrorists. Pelousy put up a Wall around the Capitol Building ringed with armed Guardsmen and Reservists for several months last year. Nancy felt safer then. Which was the important thing.

#SharterJoe has seen the glowing example that is Pelousy and he wants to follow her lead.

An interesting glance:

In the United States, Former President Donald Trump made worldwide headlines with his push to build a wall along the United States-Mexico border in order to keep out illegal immigrants. While many people have vocalized their opposition to the plan, the United States would not be the first nation to construct a wall along its border. Around the world, there are several nations that have border walls, fences, or barriers. These usually serve the purpose of controlling the border, keeping out illegal immigrants and preventing smuggling. Other nations use barriers when there are disputed or unclear borders.

As of December 2021, border walls are located in the following nations: North Korea and South Korea; Hong Kong; South Africa and Mozambique; Egypt; Kuwait and Iraq; Spain; Uzbekistan and Kyrgyzstan; South Africa; Turkmenistan and Uzbekistan; Uzbekistan and Afghanistan; Botswana and Zimbabwe; India; Saudi Arabia and Yemen; Brunei and Limbang; Kazakhstan and Uzbekistan; Bulgaria; Saudi Arabia and Iraq; Hungary; Macedonia, and Israel.

There are also several proposed and planned barriers between Belize and Guatemala; Costa Rica and Nicaragua; Thailand and Malaysia, and the United States. Some nations have their barriers under construction, including India and Bangladesh; India and Myanmar; Iran and Pakistan; and Ukraine and Russia. Poland and Belarus announced a border wall in 2021 to prevent illegal immigration.The Dominican Republic and Haiti also announced a border wall this year. The Pakistan-Afghanistan border was built in 2021 and the Greece-Turkey border was expanded.
